YGL063C-A Antibody

What is YGL063C-A and what is its significance in yeast research?

YGL063C-A is a protein encoded in Saccharomyces cerevisiae (baker's yeast) that appears to be involved in chromatin regulation and DNA organization processes. While not extensively characterized compared to more widely studied yeast proteins, it may have functional relationships with macromolecular complexes involved in chromatin modification, such as those containing histone acetyltransferases and deacetylases. Research indicates potential connections to essential cellular processes governed by acetylation states, as suggested by genetic interaction studies examining NuA4 complex activities .

The protein's significance stems from its potential role in fundamental biological processes involving DNA organization, which are conserved across eukaryotes. Studying YGL063C-A can contribute to our understanding of chromatin regulation and potentially inform broader questions about eukaryotic gene expression control mechanisms.

What specific applications are YGL063C-A antibodies validated for?

YGL063C-A antibodies are primarily validated for enzyme-linked immunosorbent assay (ELISA) and Western blot (WB) applications . These techniques allow researchers to detect and quantify YGL063C-A protein in yeast samples. The antibodies are specifically reactive with Saccharomyces cerevisiae (strain ATCC 204508 / S288c), making them suitable for targeted research on this model organism .

When designing experiments with these antibodies, researchers should consider that:

• ELISA applications allow for quantitative measurement of YGL063C-A in solution

• Western blot applications permit detection of the protein in cell lysates with size discrimination

• The antibodies are affinity-purified, which enhances their specificity for the target protein

• Current validation does not extend to other techniques such as immunoprecipitation or immunohistochemistry without additional validation steps

What are the optimal storage and handling conditions for YGL063C-A antibodies?

For maximum stability and performance of YGL063C-A antibodies, researchers should adhere to the following storage and handling recommendations:

• The antibodies are provided in a protective buffer containing 50% glycerol, 0.01M PBS (pH 7.4), and 0.03% Proclin 300 as a preservative

• When working with the antibody, keep it on ice and return to storage promptly

• Consider aliquoting the antibody upon initial thawing to minimize freeze-thaw cycles

Long-term stability testing data for these specific antibodies is not provided in the available literature, but generally, polyclonal antibodies stored under optimal conditions can maintain activity for several years.

How should researchers design validation experiments for YGL063C-A antibodies?

Proper validation of YGL063C-A antibodies is essential for generating reliable research data. Based on antibody validation principles outlined by the International Working Group for Antibody Validation, researchers should implement a multi-faceted validation approach :
