YLR282C Antibody

What is YLR282C and what is its significance in yeast research?

YLR282C refers to a specific gene locus in Saccharomyces cerevisiae (Baker's yeast), particularly in the reference strain ATCC 204508 / S288c. This gene encodes a protein with Uniprot accession number O13542, which is the target of the corresponding antibody . Understanding the function and interactions of this protein is crucial for yeast biology research, as S. cerevisiae serves as an important model organism for eukaryotic cell biology. The YLR282C antibody (product code CSB-PA519276XA01SVG) enables researchers to detect, quantify, and localize this protein in experimental settings.

For researchers initiating work with this antibody, it's important to familiarize yourself with the available literature on YLR282C function and the specific characteristics of the antibody preparation you're using. This preliminary research will inform proper experimental design and interpretation of results.
