Phospho-Lyn (Tyr507) Antibody in Immunofluorescence (IF) — Immunofluorescence was performed on fixed and permeabilized Jurkat cells treated with Pervanadate (100 uMl/ 60 min) for detection of Lyn (pY507) using Anti-Lyn (pY507)Rabbit Polyclonal Antibody (Product # 720013, 2 µg/mL) and labeled with Goat anti-Rabbit IgG (H+L) Superclonal™ Secondary Antibody, Alexa Fluor® 488 conjugate (Product # A27034, 0.4 µg/mL, 1:2500). Panel a) shows representative cells that were stained for detection and localization of Lyn (pY507) protein (green), Panel b) is stained for nuclei (blue) using SlowFade® Gold Antifade Mountant with DAPI (Product # S36938, 1:50). Panel c) represents cytoskeletal F-actin staining using Alexa Fluor® 594 Phalloidin (Product # A12381, 1:200). Panel d) is a composite image of Panels a, b and c clearly demonstrating nuclear localization of Lyn (pY507). Panel e) represents control cells with no primary antibody to assess background.

Phospho-Lyn (Tyr507) Antibody in Western Blot (WB) — Western blot analysis was performed on whole cell extracts (20 µg lysate) of Jurkat (lane1), Jurkat treated with Pervanadate (100 uM/ 60min) (lane2), K562 (lane3) and K562 treated with Pervanadate (100 uM/ 60min) (lane4). The blots were probed with Anti-Lyn (pY507)Rabbit Polyclonal Antibody (Product # 720013, 0.5-2 µg/mL) and detected by chemiluminescence using Goat anti-Rabbit IgG (H+L) Superclonal Secondary Antibody, HRP conjugate (Product # A27036, 0.4 µg/mL, 1:2500 dilution). A clear 45 kDa band corresponding to Lyn (pY507) was observed across cell lines tested according to the treatment. Known quantity of protein samples were electrophoresed using Novex®NuPAGE®4-12% Bis-Tris gel (Product # NP0321BOX), XCell SureLock Electrophoresis System (Product # EI0002), and Novex® Sharp Pre-Stained Protein Standard (Product # LC5800). Resolved proteins were then transferred onto a nitrocellulose membrane with iBlot® Dry Blotting System (Product # IB21001). The membrane was probed with the relevant primary and secondary antibody following blocking with 5% skimmed milk. Chemiluminescent detection was performed using Pierce™ ECL Western Blotting Substrate (Product # 32106).

Phospho-Lyn (Tyr507) Antibody in Cell treatment — Altered expression of proteins upon cell treatment demonstrates antibody specificity. Western blot using Phospho-Lyn (Tyr507) Polyclonal Antibody (Product # 720013), shows increased expression of proteins phosphorylated at the tyrosine residues in Jurkat and K562 cell lines upon treatment with Pervanadate. {TM}

Target Information

Lyn proto oncogene (Lcl/Yes related novel protein tyrosine kinase) is encoded by the Lyn gene located on chromosome 8 in humans and belongs to the Src family kinase. It is a non-receptor tyrosine kinase that acts as a mediator in transducing cellular signaling. The most well studied expression of Lyn is in hematopoietic cell types, both lymphoid and myeloid cells with exclusion in T lymphocytes. It has also been observed that Lyn plays diverse roles such as in regulation of B cell receptor signaling, mast cell signaling and Epithelial - Mesenchymal Transition (EMT).
