SPBC947.06c Antibody

What is SPBC947.06c Antibody and what organism does it target?

SPBC947.06c Antibody is a polyclonal antibody specifically designed to target the SPBC947.06c protein from Schizosaccharomyces pombe (strain 972 / ATCC 24843), commonly known as fission yeast. This antibody has been developed using a recombinant S. pombe SPBC947.06c protein as the immunogen, which ensures specificity for its target organism . The antibody corresponds to the UniProt accession number O43081, which researchers can reference for detailed protein information. When designing experiments, it's essential to consider that this antibody has been specifically validated for S. pombe and may not exhibit cross-reactivity with proteins from other species.

What applications has SPBC947.06c Antibody been validated for?

The SPBC947.06c Antibody has been specifically validated for two primary applications:

• ELISA (Enzyme-Linked Immunosorbent Assay): Suitable for detecting the target protein in solution-based immunoassays.

• Western Blot (WB): Validated for detecting denatured SPBC947.06c protein in cell or tissue lysates .

These validated applications provide researchers with reliable methods for detecting and quantifying SPBC947.06c protein. When planning experiments, researchers should optimize protocols for these specific applications rather than assuming functionality in other immunological techniques without prior validation.

What are the optimal storage conditions for SPBC947.06c Antibody?

The optimal storage conditions for maintaining SPBC947.06c Antibody activity are:

• Upon receipt, store at either -20°C or -80°C

• Avoid repeated freeze-thaw cycles, which can significantly decrease antibody activity

• The antibody is supplied in a storage buffer containing 0.03% Proclin 300, 50% Glycerol, and 0.01M PBS at pH 7.4

The inclusion of glycerol in the storage buffer helps prevent ice crystal formation during freezing, which can damage antibody structure. For working solutions, small aliquots should be prepared to minimize freeze-thaw cycles.

What is the composition and purification method of SPBC947.06c Antibody?

SPBC947.06c Antibody is:

• A rabbit-derived polyclonal IgG antibody

• Supplied in liquid form

• Purified using antigen affinity chromatography methods

• Formulated in a buffer containing 0.03% Proclin 300 (preservative), 50% Glycerol, and 0.01M PBS at pH 7.4

The antigen affinity purification method specifically isolates antibodies that bind to the target antigen, resulting in higher specificity compared to protein A/G purification methods. This purification approach reduces background and non-specific binding in experimental applications.

What methodological considerations should researchers address when optimizing Western blot protocols for SPBC947.06c Antibody?

When optimizing Western blot protocols for SPBC947.06c Antibody, researchers should consider the following methodological aspects:

• Sample preparation: Fission yeast cells require specific lysis conditions due to their robust cell walls. Consider using glass bead disruption or enzymatic methods with zymolyase before standard lysis buffer treatment.

• Blocking optimization: Test different blocking agents (5% BSA vs. 5% non-fat milk) as the high glycerol content (50%) in the antibody formulation may interact differently with various blocking reagents .

• Dilution optimization: Begin with a 1:1000 dilution (similar to tested antibodies like PPCS [EPR9453]) and perform a dilution series (1:500-1:5000) to determine optimal signal-to-noise ratio.

• Exposure considerations: Due to potential variability in expression levels of SPBC947.06c in fission yeast, test multiple exposure times to capture the appropriate signal intensity.

• Controls: Include both positive controls (purified recombinant SPBC947.06c protein) and negative controls (lysates from SPBC947.06c knockout strains if available) to validate specificity.

This methodological approach mirrors standard practices used for validating antibodies in well-established systems, as demonstrated in the validation of PPCS antibody across multiple human cell lines .

How can researchers validate the specificity of SPBC947.06c Antibody in experimental systems?

Validating antibody specificity is crucial for generating reliable scientific data. For SPBC947.06c Antibody, researchers should implement a multi-faceted validation approach:

• Genetic validation: Test the antibody in wild-type strains versus SPBC947.06c deletion/knockout strains. Absence of signal in the knockout strain strongly supports specificity.

• Epitope competition assay: Pre-incubate the antibody with excess recombinant SPBC947.06c protein before application. Signal reduction indicates specific binding.

• Orthogonal detection methods: Correlate antibody-based detection with orthogonal methods such as mass spectrometry or RNA expression data.

• Cross-reactivity assessment: Test against related proteins in S. pombe to ensure the antibody doesn't recognize homologous proteins.

• Immunoprecipitation followed by mass spectrometry: Confirm that the immunoprecipitated protein matches SPBC947.06c through peptide identification.

This multi-method validation strategy aligns with contemporary antibody validation practices that emphasize corroboration across different experimental approaches, similar to the validation methodology employed for therapeutic antibodies such as those targeting staphylococcal enterotoxin B .

What experimental design considerations are important when using SPBC947.06c Antibody for studying protein-protein interactions?
