YCR045W-A Antibody

What is YCR045W-A and what cellular functions is it associated with?

YCR045W-A is a gene locus in Saccharomyces cerevisiae (baker's yeast), specifically in the reference genome of laboratory strain S288C. The gene encodes a protein that has been cataloged in the Saccharomyces Genome Database (SGD) with UniProt accession number Q8TGQ2 . While specific functions have not been extensively characterized in the provided literature, the protein is significant enough to warrant antibody development for research purposes.

The protein's analysis requires sophisticated molecular biology techniques including Western blotting and ELISA, suggesting it may play roles in cellular processes important enough to merit investigation in yeast model systems. Researchers typically investigate such proteins to understand fundamental eukaryotic processes, as S. cerevisiae serves as an important model organism due to its simple cellular organization and relevance to the study of physiological processes in metazoan cells .

What sample preparation methods are recommended for optimal detection of YCR045W-A protein?

When preparing samples for YCR045W-A protein detection, researchers should follow these methodological steps:

• Cell lysis protocol: Harvest yeast cells in mid-log phase (OD600 ≈ 0.8-1.0) and wash twice with cold PBS. Lyse cells using either glass bead disruption in appropriate lysis buffer (50 mM Tris-HCl pH 7.5, 150 mM NaCl, 1 mM EDTA, 1% Triton X-100) or enzymatic digestion of the cell wall with zymolyase followed by gentle disruption.

• Protein extraction optimization: Include protease inhibitors (PMSF, leupeptin, pepstatin) in all buffers to prevent degradation. For membrane-associated proteins, consider specialized detergent-based extraction methods.

• Sample quantification: Determine protein concentration using Bradford or BCA assay and normalize loading amounts (typically 20-50 μg total protein per lane for Western blot).

• Sample denaturation: Heat samples at 95°C for 5 minutes in Laemmli buffer containing SDS and β-mercaptoethanol to ensure complete denaturation before gel loading .

For immunoprecipitation applications, use gentler lysis conditions to preserve protein-protein interactions and native conformations that may be recognized by the antibody.

What are the recommended applications and experimental conditions for YCR045W-A antibody?

The YCR045W-A antibody has been specifically tested and validated for the following applications:

• Western Blotting (WB): Recommended dilution ranges from 1:500 to 1:2000 in 5% non-fat milk or BSA in TBST. Optimal incubation is overnight at 4°C or 2 hours at room temperature. This application is particularly useful for detecting the presence and relative abundance of YCR045W-A protein in cell lysates or purified samples .

• Enzyme-Linked Immunosorbent Assay (ELISA): Typically used at dilutions between 1:1000 and 1:5000, depending on the sensitivity required. This method allows for quantitative analysis of YCR045W-A protein levels across multiple samples .

When designing experiments, consider these technical parameters:

• The antibody specifically reacts with Saccharomyces cerevisiae strain ATCC 204508/S288c (Baker's yeast)

• It is affinity-purified against recombinant YCR045W-A protein, enhancing specificity

• It is stored in a buffer containing 50% glycerol and 0.01M PBS (pH 7.4) with 0.03% Proclin 300 as a preservative

For experimental consistency, always include appropriate positive and negative controls, and validate the antibody's specificity in your specific experimental conditions before conducting full-scale experiments.

What are the optimal storage conditions for maintaining YCR045W-A antibody activity?

To maximize the shelf life and performance of YCR045W-A antibody, adhere to these storage protocols:

• Long-term storage: Upon receipt, store the antibody at -20°C or preferably -80°C for maximum stability. The antibody is provided in a buffer containing 50% glycerol, which prevents freeze-thaw damage and allows for storage in non-frost-free freezers .

• Avoid repeated freeze-thaw cycles: Each freeze-thaw cycle can reduce antibody activity by approximately 10-15%. To minimize this, aliquot the antibody into smaller volumes based on typical usage before freezing .

• Working solution handling: When preparing working dilutions, use sterile technique and clean tubes. Working dilutions should be prepared fresh for each experiment and can be stored at 4°C for up to one week if preserved with 0.02% sodium azide.

• Shipping and temporary storage: If temporary storage at 4°C is necessary (< 1 week), ensure the antibody is kept in its original buffer and protected from light. Return to -20°C or -80°C as soon as possible.

The storage buffer (0.01M PBS, pH 7.4 with 50% glycerol and 0.03% Proclin 300) provides optimal conditions for maintaining antibody stability while preventing microbial growth .
