Anti-LCK Antibody

Manufactured by Antibodies.com, this research-grade rabbit polyclonal reagent is raised against LCK (Lck), a Src-family tyrosine kinase involved in T-cell receptor signalling, and is supplied as an affinity-purified antiserum at 1.0 mg/mL in a 50 µL vial. The antibody was generated using a recombinant human LCK protein as immunogen and recognises the endogenous total LCK protein in samples from human, mouse and rat origins, making it suitable for cross-species studies in immunology and cell signalling research. Validated applications include Western blotting (WB) and immunohistochemistry (IHC), where it can be used to probe LCK expression in lymphoid tissues and cultured cells. The host species is rabbit, the clonality is polyclonal, and the preparation is unconjugated, allowing users to pair it with their own secondary detection reagents or to conjugate it for custom assays. The antibody is formulated in phosphate-buffered saline at pH 7.4 (without Mg²⁺ and Ca²⁺), containing 150 mM NaCl, 0.02% sodium azide and 50% glycerol as a cryoprotectant, and it is recommended to be stored at –20 °C with avoidance of repeated freeze/thaw cycles to preserve activity. Each lot is intended for research use only and is not cleared for diagnostic or therapeutic applications; the product is shipped from Antibodies.com's St. Louis, MO facility with a typical lead time of 6–9 business days, ensuring reliable cold-chain delivery to laboratories worldwide.
