TGAL11 Antibody

What is TGAL11 Antibody and what is its target protein?

TGAL11 Antibody (product code: CSB-PA200772XA01OFG) is a polyclonal antibody developed against the TGAL11 protein from Oryza sativa subsp. japonica (rice). It is specifically raised in rabbits using recombinant TGAL11 protein as the immunogen and has been affinity-purified to enhance specificity. This antibody is designed exclusively for research applications and should not be used for diagnostic or therapeutic purposes. The target protein, TGAL11 (UniProt accession: Q2QXL0), is expressed in rice and belongs to a family of proteins involved in plant developmental processes .

What are the recommended storage conditions for TGAL11 Antibody?

TGAL11 Antibody should be stored at either -20°C or -80°C immediately upon receipt. It is critical to avoid repeated freeze-thaw cycles as these can compromise antibody functionality and affinity. The antibody is provided in a storage buffer containing 0.03% Proclin 300 as a preservative, 50% glycerol, and 0.01M PBS at pH 7.4, which helps maintain stability during long-term storage. For working solutions, store at 4°C for short-term use (1-2 weeks) and prepare fresh dilutions for optimal performance in experimental applications .

What applications has TGAL11 Antibody been validated for?

TGAL11 Antibody has been specifically tested and validated for Enzyme-Linked Immunosorbent Assay (ELISA) and Western Blotting (WB) applications. These applications allow researchers to detect, quantify, and characterize the TGAL11 protein in rice samples. When employing this antibody in untested applications such as immunohistochemistry or immunofluorescence, researchers should conduct preliminary validation experiments with appropriate positive and negative controls to establish optimal working conditions .

What are the recommended working dilutions for different applications?

Optimal working dilutions for TGAL11 Antibody vary by application and should be determined empirically for each experiment. Based on standard protocols for similar polyclonal antibodies in plant research, the following ranges can serve as starting points:

• Secondary antibody control: Sample processed with secondary antibody only (omitting TGAL11 primary antibody)

• Blocking peptide control: Pre-incubation of TGAL11 Antibody with its immunogenic peptide to confirm specificity

Inclusion of these controls helps distinguish between specific binding and background signals, supporting confident interpretation of experimental results.

How can I validate the specificity of TGAL11 Antibody for my particular research?

Validating antibody specificity is crucial for obtaining reliable results. For TGAL11 Antibody, consider implementing these validation approaches:
