IKI1 Antibody

What is the IKI1 Antibody and what organism does it target?

IKI1 Antibody is a polyclonal antibody raised against recombinant Saccharomyces cerevisiae (Baker's yeast) IKI1 protein. It specifically reacts with S. cerevisiae (strain ATCC 204508/S288c) and is intended for research applications only. This antibody is produced in rabbits and purified using antigen affinity methods to ensure specificity for the target protein . Its primary applications include ELISA and Western Blot analyses for the identification and study of IKI1 protein in yeast systems.

What are the recommended storage conditions for IKI1 Antibody?

Upon receipt, IKI1 Antibody should be stored at -20°C or -80°C to maintain its activity and specificity. Repeated freeze-thaw cycles should be avoided as they can lead to protein denaturation and loss of antibody function. The antibody is typically supplied in a liquid form containing 50% glycerol, 0.01M PBS (pH 7.4), and 0.03% Proclin 300 as a preservative . This storage buffer helps maintain antibody stability during long-term storage and prevents microbial contamination.
