Description

Description: The monoclonal antibody 2F12 recognizes human, mouse, and rat ITK. ITK (also known as Interleukin-2 inducible T-cell kinase, T-cell-specific kinase, Tyrosine-protein kinase Lyk, Emt, and Tsk) is a member of the Tec family of kinases that include Tec, Btk, Bmx, and Txk. Tec family kinases play an indispensable role in activation of phospholipase C and activation of calcium-dependent signaling cascades following antigen receptor triggering. ITK is highly expressed by T cells and is required for optimal TCR-induced PLCgamma1 activation. Mice congenitally lacking ITK show profound defects in T cell development and signaling. Defects in ITK are the cause of lymphoproliferative syndrome EBV-associated autosomal type 1 (LPSA1). ITK also plays a role in the development of various T cell mediated inflammatory disorders such as atopic dermatitis, psoriasis, and allergic asthma.

Experimental details

Western blot was performed using Anti-ITK Monoclonal Antibody (2F12), eBioscience™ (Product # 14-9752-82) and a 71 kDa band corresponding to Tyrosine-protein kinase ITK/TSK was detected in the T-cell (Jurkat and MOLT-4) and natural killer cell line (NK-92) but not in B-cell lines (Raji and Ramos) and THP-1 monocyte. Whole cell extracts (40 µg lysate) of Jurkat (Lane 1), MOLT-4 (Lane 2), Raji (Lane 3), Ramos (Lane 4), THP-1 (Lane 5), NK-92 (Lane 6), Mouse Heart (Lane 7), Mouse Skeletal Muscle (Lane 8) and Mouse Thymus (Lane 9) were electrophoresed using NuPAGE™ 10% Bis-Tris Protein Gel (Product # NP0301BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The blot was probed with the primary antibody (1:1000 dilution) and detected by chemiluminescence with Goat anti-Mouse IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A28177, 1:10000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using SuperSignal™ West Atto Ultimate Sensitivity Substrate (Product # A38556). The band detected at ~25 kDa corresponds to the free circulating IgG detected in mouse tissues.
