ART10 Antibody

What is ART10 Antibody and what specific targets does it recognize?

ART10 Antibody is a research-grade polyclonal antibody raised in rabbits that demonstrates specificity for ART10 protein targets. Based on available research, this antibody shows reactivity with Ashbya gossypii (strain ATCC 10895 / CBS 109.51 / FGSC 9923 / NRRL Y-1056), also known as Eremothecium gossypii, a filamentous fungus used as a model organism . The antibody is designed for research applications including Western blotting, immunohistochemistry, and enzyme-linked immunosorbent assays (ELISA).

What is the recommended storage and reconstitution protocol for ART10 Antibody?

For optimal antibody performance, ART10 Antibody should be stored following protocols similar to those established for other research antibodies. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. Most research antibodies maintain stability for approximately 12 months from date of receipt when stored at -20 to -70°C as supplied. After reconstitution, the antibody typically remains stable for 1 month at 2 to 8°C under sterile conditions, or 6 months at -20 to -70°C under sterile conditions . Always perform a small-scale validation test after reconstitution to ensure antibody functionality is preserved.

How should I design validation experiments to confirm ART10 Antibody specificity?

Designing robust validation experiments is crucial for confirming antibody specificity. A comprehensive validation approach should include:

• Western blot analysis using positive control samples (tissues/cells known to express the target) and negative control samples (tissues/cells with confirmed absence of target expression)

• Peptide competition assays where pre-incubation of the antibody with its antigenic peptide should abolish signal

• Knockout/knockdown validation using genetic models lacking the target protein

• Cross-reactivity testing against structurally similar proteins

For membrane proteins, use both reducing and non-reducing conditions during Western blot analysis, as this can significantly affect epitope accessibility and recognition patterns . Document molecular weight markers clearly and note any unexpected bands that may represent post-translational modifications or proteolytic fragments.

What methodological approaches can optimize ART10 Antibody performance in immunohistochemistry?

Optimizing immunohistochemistry protocols for ART10 Antibody requires systematic evaluation of multiple parameters:

• Blocking conditions: Evaluate different blocking reagents (BSA, normal serum, commercial blockers) at varying concentrations (1-10%)

• Antibody concentration: Perform titration experiments (typically 1-20 μg/mL) to determine optimal signal-to-noise ratio

• Incubation conditions: Compare room temperature versus 4°C overnight incubation

• Detection systems: Evaluate chromogenic (HRP-DAB) versus fluorescence-based detection methods

Following protocols similar to those used for other research antibodies, specific staining patterns should be documented and compared with known expression patterns of the target protein .
