Where can I physically get a large library of protein genes?

I am studying massively parallel protein-protein interaction. Is there a good source for a ready DNA library, where a protein gene (or part of it) would be surrounded by standard adapters? Like...

Can aminoacyl tRNA synthetase attach a polypeptide to tRNA instead of single amino acid?

Typical function of aminoacyl tRNA synthetase (aaRS) is to attach amino acid to tRNA for following protein synthesis. I am curious, is there a natural process (or engineered aaRS), which would...

How many electrons are needed to reduce [2Fe-2S] adrenodoxin (ferredoxin)?

Am I right that [2Fe-2S] adrenodoxin (or ferredoxin) molecule is reduced (and can carry) one electron at a time? I've read several papers claiming that Adx + 1e- --> Adx-but not Adx + 2e-...

Which method to use to purify lentivirus packaging plasmids? Will classic maxi-prep work?

I'm trying to purify lentivirus packaging plasmids for future lentivirus production. I've heard the opinion, that simple maxi-prep yields DNA with endotoxins, which reduces the virus titration. To...

Is there a process of polynucleotide synthesis from nucleoside monophosphate, using energy from external chemical reaction?

Normally, DNA and RNA polymerization is realized by polymerases, using nucleoside triphosphates. The energy for the reaction is obtained from chopping off diphosphate group. I'm curious: is there...

Can I make conclusions about certain protein redox states based on the redox state of cytoplasm?

Say, I have a protein in cytoplasm, which redox potential measured in vitro is +200 mV. The redox potential of cytoplasm appears to be say +50 eV. Knowing that, can I conclude that my protein is...

How to link a protein to a DNA oligonucleotide?

I need to link a protein to a DNA oligonucleotide. Protein must remain active. Linkage must be at a specific site (all proteins must be linked at the same site). How would you do that? Did anyone...
