Ubiquitin

Ubiquitin is a small regulatory protein that is ubiquitous in eukaryotes. Ubiquitination (or Ubiquitylation) refers to the post-translational modification of a protein by the covalent attachment (via an isopeptide bond) of one or more ubiquitin monomers. Ubiquitin (originally, Ubiquitous Immunopoeitic Polypeptide) was first identified in 1975 as an 8.5 kDa protein of unknown function expressed universally in living cells.

immunohistochemistry with mouse skin

Aha! Innervation! You can help me then! Yay! I am planning to apply IHC to investigate innervation of some viscerals. Hypothetically, it involves ubiquitin system, thus I need primary Ab for ubiquitin. Through references, they suggest me to use PGP 9.5. Unfortunately, I am out of that stuff and ...

tissue-specific protein database?

Hmm I remember I used this for one of my research. I worked on ubiquitin. Give me time to find the site. It is a very good one I believe :?
