YKL065W-A Antibody

What is YKL065W-A Antibody and what are its key specifications?

YKL065W-A antibody (product code CSB-PA649634XA01SVG) is a polyclonal antibody raised in rabbits against recombinant Saccharomyces cerevisiae (strain ATCC 204508/S288c) YKL065W-A protein. This antibody has been developed specifically to recognize the YKL065W-A protein (UniProt accession: Q2V2P2) in Baker's yeast. The antibody is supplied in liquid form, non-conjugated, and is purified using antigen affinity purification methods. It is classified as an IgG isotype polyclonal antibody and is intended exclusively for research applications, not for diagnostic or therapeutic use .

The antibody is provided in a storage buffer containing 0.03% Proclin 300 as a preservative, 50% glycerol, and 0.01M PBS at pH 7.4, which helps maintain its stability and activity during storage and experimental use .

What are the validated applications for YKL065W-A Antibody?

YKL065W-A antibody has been tested and validated for the following applications:

• Enzyme-Linked Immunosorbent Assay (ELISA): For quantitative detection of YKL065W-A protein in solutions or biological samples.

• Western Blotting (WB): For identification and semi-quantitative analysis of YKL065W-A protein in complex protein mixtures .

These validated applications ensure reliable detection and identification of the target antigen in appropriate experimental contexts. When establishing new applications or experimental conditions, preliminary validation is recommended to confirm antibody performance in your specific research system.

What are the optimal storage and handling conditions for YKL065W-A Antibody?

To maintain optimal activity and stability, YKL065W-A antibody should be stored at -20°C or -80°C upon receipt. The antibody is supplied in a buffer containing 50% glycerol to prevent freezing at -20°C, which allows for easy aliquoting without repeated freeze-thaw cycles.
