"With MRFM, the sample to be examined is attached to the end of a tiny silicon cantilever (about 100 millionths of a meter long and 100 billionths of a meter wide). As a magnetic iron cobalt tip moves close to the sample, the atoms’ nuclear spins become attracted to it and generate a small force on the cantilever. The spins are then repeatedly flipped, causing the cantilever to gently sway back and forth in a synchronous motion. That displacement is measured with a laser beam to create a series of 2-D images of the sample, which are combined to generate a 3-D image."

Fwd: primer design guide

Hi Mac,
I've started using geneious for primer design, it uses primers3 but
with a nicer interface.  I know you can make primers with the 30 day
free trial and maybe after that with the limited version.   Genious is
a really nice tool in general for organizing and playing around with
sequences, although for high throughput stuff it is not the right
tool.

Cheers,
John

Thanks,
the square brackets fixed things as far as getting the coding sequence
inside the primers... now do you know if there is a way to tell it
specifically where to start and stop? or should I just remove the UTR
regions if I don't want to prime on them?
can you tell me if I need to be concerned with removing or chopping
the untranslated regions? What are their purposes? I am thinking of
ligating this cDNA into a vector that has a his-tag or a translocation
sequence (if I use it in yeast for secretion).
Again thanks a lot, great stuff to know (even though I could have got
it out of a prof in 5 minutes, its gonna stick with me now for sure)

To: ssi_list@yahoogroups.com


 

FYI,

"3-D Printing Device Could Build Moon Base from Lunar Dust"
Space.com
http://www.space.com/businesstechnology/3-d-printer-moon-base-100416.html

: Future astronauts might end up living in a moon base created
: largely from lunar dust and regolith, if a giant 3-D printing
: device can work on the lunar surface.

: The print-on-demand technology, known as D-Shape, could save on
: launch and transportation costs for manned missions to the moon.
: But the concept must first prove itself in exploratory tests funded
: by the European Space Agency (ESA)

: "We will make very basic printing trials in a vacuum environment to
: verify if this is possible," said Enrico Dini, chairman of Monolite
: UK Ltd and creator of D-Shape.

: Dini's D-Shape has created full-size sandstone buildings on Earth
: by using a 3-D printing process similar to how inkjet printers
: work. It adds a special inorganic binder to sand so that it can
: build a structure from the bottom up, one layer at a time.

: The device raises its printer head by just 5 to 10 millimeters for
: each layer, moving from side to side on horizontal beams as well as
: up and down on four metal frame columns. Finished structures end
: made out of a marble-like material that's superior to certain types
: of cement. The buildings do not require iron reinforcing.

: Such a concept might help future lunar colonists live off the land,
: as well as provide thick-walled structures that protect against
: solar storms or micrometeorites.

: Space agencies have already begun testing other technologies meant
: to mine water and oxygen from the lunar regolith. NASA scientists
: have also played with possible recipes for a sort of lunar concrete
: based on moon dust.

: But D-Shape offers the added attraction of having a somewhat
: straightforward building process that does not require huge amounts
: of construction machinery or many robot laborers.

: Making the device work in a lunar environment may yet prove tricky.
: A first challenge involves making D-Shape function within the
: vacuum environment on a moon that lacks any meaningful atmospheric
: pressure. But Dini remains self-admittedly optimistic by nature.

: "I'm not a scientist and I'm not a technician — I'm an inventor,"
: Dini told SPACE.com. He spent five years "facing unexpected issues
: and finding unexpected solutions" when he first designed D-Shape,
: before heeding the call from ESA.

: Dini's Monolite has teamed up with an Italian aerospace firm called
: Alta, which has a large vacuum chamber in its Pisa facilities. They
: hope to build a small structure perhaps just 3 feet (1 meter) on
: each side during the vacuum trials.

: Other partners working on the ESA project include Foster+Partners,
: a UK architecture firm, and Scuola Superiore Sant'Anna Perceptual
: Robotics Laboratory, an Italian lab that specializes in robotics
: and automation.

: A second challenge comes from the cost of running D-Shape trials by
: using expensive lunar regolith simulant. Dini has tried developing
: a possible alternative to NASA's JSC-1 simulant that might work for
: his research. Structures built from such material will have to
: undergo resistance testing.

: Even a functional D-Shape that works with lunar regolith would
: still face building limitations based on the amount of binder that
: a rocket could carry to the moon. Yet success would mean
: transforming lunar dust into part of the solution, rather than just
: a problem for astronauts and robotic explorers.

: NASA researchers have experimented with a different type of on-site
: manufacturing device that could someday create spare parts or new
: materials for the International Space Station. D-Shape could also
: end up deploying beyond Earth for additional testing, if all goes
: well with the first phase.

: The most important trials will be done in outer space," Dini said.

I loaded the new firmware and also had issues getting up to the right
temperature.  My extruder was set to 230 but only ever got to 175, and
my platform was set to 100 but only got heated up to 75.  Rolling back
to the previous extruder firmware returns my Makerbot to working
order. Anyone have any idea why the new firmware has these issues?

Fwd: What kits do people prefer for cDNA synth, and why?

To: diybio@googlegroups.com


The kit I used this morning included AMV reverse transcriptase, which has higher functioning temp which is better for denaturing secondary RNA structures... not sure how big a problem that is with mRNA.

It doesn't seem like RNase H activity is much of a problem since I'm looking to amplify only a certain mRNA, rather than make a library... does that make sense, or is RNase H activity just bad/useless ?

I am looking for cDNA synth kits and settled on this one at $4.33 a reaction:

I was settled actually, until I used a promega kit this morning after doing a trizol-chloroform RNA extraction. My professor said that trizol is cheap and yields high amounts of RNA, and said that he uses the promega kit because our school prefers to order through VWR... I am still waiting to hear if we get a discount through VWR or not.

If anyone has opinions about the kit I posted through NEB, or has a better recommendation please send quickly, as I'm trying to purchase stuff tomorrow, or at least have money set aside for its purchase.

We have an ABI PRISM 310, an older model single-capillary sequencer. There is an electrical fault somewhere, which we are still in the process of hunting down / fixing. I'm not personally familiar with its materials (I'm used to just working with the data afterwards), but once we have it up and running I'm sure we'd happy to help test out your kit however we can.

Also, a general question about sanger sequencing: I'm probably going to use Taq, but I might purchase a higher-fidelity / higher-processivity polymerase.  What sort of read lengths could I typically get from a commercial sanger sequencing provider?  Like, 700-1000 bp?  I would be interested in amplifying like 5kb, if possible.

Cheers,
Mac

Subject: Sequencer update
To: socal-diybio@googlegroups.com


Hey folks,

Things are moving slowly forward with our lovely sequencer, but I
thought it good to put all the docs and whatnot we've managed to find
together in one place. I've found a protocol for using it, a Windows
installer for ABI sequence analysis software (good to convert it into
a non-proprietary format for us to work with) and user's manuals for
the diagnostics system and the sequencer overall. I added links to all
that to the Lab Protocol wiki page, though I imagine it should have
its own page at some point. I'll likely be adding more this afternoon
as I find it.

Here's the link again for those that may have forgotten, or not made
accounts yet:

And of course feel free to edit and add more stuff as you like.

Does anyone know of a reliable wet chemical silicon etch (isotropic or anisotropic) which can be masked by photo resist? I need to etch down 10um.

  1. Remove TDTS cover from wafer? (Lukas Bogunovic)

Subject: [mems-talk] Remove TDTS cover from wafer?
Hi folks,

i have a question concerning
Tridecafluor-1,1,2,2-tetra-hydrooctyl-trichlorosilane (TDTS).

Before we do softlithography with PDMS, our wafers are covered with
vapour of this chemical. Sometimes, there are wafers that are not needed
anymore. without the tdts the su-8 structures on it can be easyly
removed with Caro's acid. That doesn't work for TDTS covered wafers -
they are highly resistant. Does anyone know how to remove this silane,
so that the wafer can be reused?

Thanks in advance!

Buenas,

As of right now we are introducing glass 3D printing on Shapeways.

You can already order these models in glass right now.

The Milky White Glass costs $5.99 per cm3, with a start-up cost of $15 per model. This price is an introductory price valid until the end of June. With this price the model below Emmanuel Lattes' Double Glass Moebius would cost $99.

moebius model in glass

It's opaque, it's porous and experimental. You can find out how glass 3D printing works & how you can get your design turned into glass here.

One very exciting thing about this is that the glass used is recycled and your models 3D printed in glass are recyclable.

Kind regards,

Joris
