SPCC553.01c Antibody

What is SPCC553.01c Antibody and what organism does it target?

SPCC553.01c Antibody is a polyclonal antibody specifically designed to recognize and bind to the SPCC553.01c protein from Schizosaccharomyces pombe (strain 972 / ATCC 24843), commonly known as fission yeast. This antibody was developed using recombinant SPCC553.01c protein as the immunogen and was raised in rabbits to produce IgG-class antibodies that have been affinity purified to ensure specificity . The target protein is associated with UniProt accession number O74939, which can be referenced for detailed protein characterization studies .

What are the optimal storage conditions for SPCC553.01c Antibody?

The antibody should be stored at -20°C or -80°C immediately upon receipt. It's critical to avoid repeated freeze-thaw cycles as these can significantly degrade antibody performance through protein denaturation and aggregation . For researchers planning long-term studies, it's advisable to prepare working aliquots in smaller volumes (typically 10-20 μL) to minimize repeated thawing of the stock solution. The antibody is supplied in a storage buffer containing 50% glycerol, 0.01M PBS (pH 7.4), and 0.03% Proclin 300 as a preservative, which helps maintain stability during storage .

What applications has SPCC553.01c Antibody been validated for?

SPCC553.01c Antibody has been specifically tested and validated for Enzyme-Linked Immunosorbent Assay (ELISA) and Western Blot (WB) applications . When designing experiments, researchers should consider that optimal working dilutions may need to be determined empirically for each specific experimental setup. For Western Blotting, starting dilutions typically range from 1:1000 to 1:5000, though optimization is essential as suggested by general antibody usage guidelines .

How should sample preparation be optimized when using SPCC553.01c Antibody for Western Blot analysis?

For optimal Western Blot results with SPCC553.01c Antibody in S. pombe studies, sample preparation requires careful consideration:

• Cell lysis: Use a buffer containing protease inhibitors to prevent degradation of the target protein. For fission yeast, mechanical disruption methods such as bead-beating are often more effective than chemical lysis.

• Protein quantification: Standardize protein loading (20-50 μg total protein per lane) using Bradford or BCA assays to ensure consistent results.

• Denaturation conditions: Heat samples at 95°C for 5 minutes in a loading buffer containing SDS and a reducing agent (DTT or β-mercaptoethanol).

• Gel percentage selection: For SPCC553.01c protein detection, choose an appropriate polyacrylamide percentage based on the protein's molecular weight to achieve optimal separation.

• Transfer conditions: Use PVDF membranes for better protein retention and signal-to-noise ratio when working with polyclonal antibodies .

When troubleshooting, consider that the recommended antibody amount for immunoprecipitation is generally 1-10 μg of purified polyclonal antibody per 200-500 μg of cell lysate protein, though this must be empirically optimized for each specific application .

What approaches can be used to validate the specificity of SPCC553.01c Antibody?

Validating antibody specificity is crucial for ensuring experimental reliability. For SPCC553.01c Antibody, consider these methodological approaches:

• Batch testing protocol: Before beginning a new experimental series, compare new antibody lots against reference standards using quantitative metrics such as EC50 values in ELISA or signal intensity ratios in Western blots.

• Storage stability assessment: Systematically evaluate antibody performance after defined storage periods (3, 6, 12 months) to establish reliable shelf-life parameters.

• Specificity monitoring: Periodically repeat cross-reactivity testing against non-target proteins to ensure maintained specificity throughout the study duration.

• Documentation system: Implement a comprehensive record-keeping system documenting antibody lot numbers, storage conditions, and performance metrics for each experimental run.

For polyclonal antibodies like SPCC553.01c Antibody, lot-to-lot variation monitoring is particularly important, as different production batches may have slightly different epitope recognition profiles .
