Microorganisms and organic preservation?

... you try simply change the water for organic solvent that will evaporate? Fix the fruit with protein linking fixative like 2% paraformaldehyde or glutaraldehyde for several days. Put the fixed fruit into serie of organic solvent concentration gradient- 30% ethanol, 50% ethanol, 70% ethanol, 96% ...

Keeping proteins from washing off the slide

... is causing the pattern to come off. I've tried washing with PBS as well as DI water. I have also tried various coatings for the slide, such as glutaraldehyde, silane derivative and agarose. The only acceptable patterning results are with bare slide. But I'm trying to keep the patterns from ...

Doing research project -- trying to configure dosages...

... this year. What I plan to do is attach a Fas (death receptor ligand) to a mesothelin antibody by binding the 2 with the protein crosslinker Glutaraldehyde. This ligand-antibody combination will then be administered to pancreatic cancer cells that overexpress mesothelin. The purpose of the ...

Re: How to be "good at the bench"

... Don’t autoclave: corrosives (Acids, phenol, bases), solvents or volatiles (ethanol, methanol. Chloroform); liquids containing bleach, formalin, or glutaraldehyde; buffers with detergents, such as 10% SDS, since they can boil over; heat labile ingredients such as serum, vitamins, antibodies, and ...

Re: dimer-homodimer-heterodimer

... That would be the simplest thing to do. Native gels are possible but tricky to do and interpret. Or you might try mild cross-linking with glutaraldehyde followed by SDS-PAGE. If you have purified what you believe to be active protein, you can do an N-terminal sequence determination. If ...
