Overview

  • Product nameAnti-Lys 20p + 21p antibody [31F5]
  • Description
    Mouse monoclonal [31F5] to Lys 20p + 21p
  • Tested applicationsSuitable for: WB, ICC/IFmore details
  • Species reactivity
    Reacts with: Saccharomyces cerevisiae
  • Immunogen

    This was raised against a yeast nucleolar prep, and screened by immunocytochemistry and western blotting. Nucleolar prep contains Lys20p protein (as well as Nop1p/fibrillarin).

  • General notes


    Lys20p and Lys21p are isozymes of yeast homocitrate synthase. They are the products of two distinct genes producing proteins of molecular weight 47.1 kDa in the case of Lys20p and 48.6kDa for Lys21p. However Lys20p and Lys21p are ~90% identical at the amino acid level and MCA-31F5 detects both proteins, revealing a doublet of stained bands on blots.
