SPBC23E6.02 Antibody

What is SPBC23E6.02 Antibody and what is its target protein's function?

SPBC23E6.02 Antibody targets a protein found in Schizosaccharomyces pombe (fission yeast), specifically strain 972/24843. This antibody is related to SPBC23E6.01c, which recognizes an RNA-binding protein involved in mRNA processing . The SPBC23E6.02 protein likely shares functional characteristics with other proteins in this family, participating in RNA metabolism pathways critical for gene expression regulation in S. pombe.

Similar to other research antibodies, SPBC23E6.02 Antibody belongs to the immunoglobulin superfamily of proteins that specifically recognize and bind to target antigens . The antibody contains variable domains with hypervariable regions that form complementarity-determining regions (CDRs), which determine binding specificity to the SPBC23E6.02 epitope .

What are the optimal storage conditions for maintaining SPBC23E6.02 Antibody activity?

For maintaining optimal activity of SPBC23E6.02 Antibody, researchers should follow these evidence-based storage protocols:

• Short-term storage (1-2 weeks): Store at 4°C with preservatives such as sodium azide (0.02%) to prevent microbial contamination.

• Long-term storage: Aliquot and store at -20°C or -80°C to avoid repeated freeze-thaw cycles, which can significantly reduce antibody activity.

• Working dilutions: Prepare fresh working dilutions on the day of experiments, as diluted antibodies lose activity more rapidly.

• Stability testing: Periodically validate antibody activity through positive control experiments when using antibody aliquots stored for extended periods.

Each laboratory should determine optimal storage conditions based on their specific reagent formulation, as preparations may contain different stabilizers and preservatives .
