OSR8 Antibody

What is OSR8 Antibody and what target does it recognize?

OSR8 Antibody (product code CSB-PA885408XA01OFG) is a polyclonal antibody raised in rabbits that specifically recognizes the OSR8 protein from Oryza sativa subsp. japonica (Rice). The antibody targets recombinant Oryza sativa subsp. japonica OSR8 protein (UniProt accession: Q9LRI7). It is purified using antigen affinity methods and stored in a buffer containing 50% glycerol, 0.01M PBS (pH 7.4), and 0.03% Proclin 300 as a preservative . The polyclonal nature of this antibody means it recognizes multiple epitopes on the target protein, potentially providing more robust detection across various experimental conditions compared to monoclonal alternatives.
