Anti-Factor 13 A (G39) Antibody

A rabbit polyclonal antibody targeting the coagulation transglutaminase Factor XIII A chain (F13A1) at the G39 epitope, supplied by Antibodies.com as an unconjugated reagent validated for Western Blot. The immunoglobulin is raised in rabbit hosts and purified to a working concentration of 1 mg/ml, formulated in PBS with 0.1% sodium azide and 50% glycerol to support cold-storage stability and reduce freeze-thaw damage during repeated use from a single aliquot.

Validated reactivity covers Human and Rat samples, supporting translational workflows that compare rodent models with patient-derived specimens. The Factor XIII A antigen is the catalytic A subunit of the plasma transglutaminase that cross-links fibrin during the final stages of clot stabilization, and the antibody enables investigations into wound remodeling, fibrotic tissue deposition, and hematopoietic lineage tracing where monocyte-derived macrophages, osteoclasts, and megakaryocytes serve as principal expression sources.

Each vial contains 50 µl of working stock, appropriate for Western Blot membranes prepared from cell lysates or tissue homogenates resolved under denaturing SDS-PAGE conditions. Researchers commonly probe whole-cell extracts at 10–20 µg per lane alongside a loading control, then detect bound antibody using an HRP-conjugated anti-rabbit secondary reagent and chemiluminescent substrate to visualize band intensity.
