YNL120C Antibody

What is YNL120C and why is it studied in Saccharomyces cerevisiae?

YNL120C is a gene/protein found in Saccharomyces cerevisiae (Baker's yeast), specifically in the reference strain ATCC 204508 / S288c. This gene is studied as part of understanding yeast cell functions, particularly in the context of polarized growth during budding and morphogenetic events in response to intracellular or extracellular cues . Like many yeast proteins, YNL120C may have functional relationships with proteins involved in cell polarity, mitosis, and cell wall maintenance, making it valuable for understanding fundamental eukaryotic cellular processes.

How should YNL120C Antibody be stored and handled?

YNL120C Antibody should be stored according to manufacturer recommendations, typically at -20°C for long-term storage. For regular use, aliquoting is recommended to avoid repeated freeze-thaw cycles that can degrade antibody quality. When working with the antibody, handle at 4°C and avoid prolonged exposure to room temperature. The commercial preparation typically comes in 0.1ml concentrated form or 2ml ready-to-use dilution . Similar to other research antibodies, proper storage conditions are critical for maintaining binding specificity and experimental reproducibility.

What validation methods confirm YNL120C Antibody specificity?

For properly validated YNL120C Antibodies, specificity would typically be confirmed through:

• Western blot analysis with yeast lysates showing a single band at the expected molecular weight

• Immunoprecipitation followed by mass spectrometry confirmation

• Comparative analysis using YNL120C knockout strains as negative controls

• Cross-reactivity testing against related yeast proteins

Similar to immunophenotyping validation procedures described for other antibodies, researchers should verify epitope recognition patterns before experimental use . When evaluating antibody specificity, consider conducting competition experiments with purified antigen to confirm binding characteristics.

How can YNL120C Antibody be used in synthetic lethal analysis frameworks?

YNL120C Antibody can serve as a valuable tool in synthetic lethal screens, particularly when investigating genetic interactions in Saccharomyces cerevisiae. In such experiments:
