Detection of Human Phospho-Lck (Y505) antibody by Western Blot.

Detection of Human Phospho-Lck (Y505) by Western Blot.

Western blot shows lysates of Jurkat human acute T cell leukemia cell line untreated (-) or treated (+) with 1 mM Pervanadate (PV) for 10 minutes or 2mM H2O2for 2 minutes. PVDF membrane was probed with 0.5 µg/mL of Mouse Anti-Human Phospho-Lck (Y505) Monoclonal Antibody (Catalog # MAB7369) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF018). A specific band was detected for Phospho-Lck (Y505) at approximately 62 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Phospho-Lck (Y505) antibody in Jurkat Human Cell Line by Immunocytochemistry (ICC).

Phospho-Lck (Y505) in Jurkat Human Cell Line.

Lck phosphorylated at Y505 was detected in immersion fixed Jurkat human acute T cell leukemia cell line stimulated (upper panel) or not (lower panel) with pervanadate using Mouse Anti-Human Phospho-Lck (Y505) Monoclonal Antibody (Catalog # MAB7369) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cell surfaces and cytoplasm. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background: Lck

Lck (p56lck) is a 56 kDa cytosolic phosphoprotein within the Src family of non-receptor tyrosine kinases. The 509 amino acid (aa) human Lck contains an SH3 domain (aa 61-121), an SH2 domain (aa 127-224) and a protein kinase domain (aa 251-259). Within aa 2-66, human Lck shares 89% aa sequence identity with mouse and rat Lck. A short (363 aa) isoform contains alternate sequence starting at aa 348, while a 539 aa isoform contains inserted sequence after aa 321. Lck interacts with T cell CD4 and CD8 molecules and plays a pivotal role in regulating T cell activation. It can be overexpressed in cancers and functions as an oncogene.
