Goat anti Human LNK antibodyrecognizes human SH2B adapter protein 3, also known as Lymphocyte-specific adapter protein Lnk or Lymphocyte adapter protein. LNK is a 575 amino acid SH2B adapter protein containing a single PH domain and a single SH2 domain. Goat anti Human LNK antibody binds to an epitope within the N-terminal region of LNK, which regulates cytokine receptor-mediated and growth factor pathways, and plays an essential role in B cell lymphopoiesis.

LNK mRNA is preferentially expressed in lymph node and spleen lymphocytes and the expression of LNK in vascular endothelial cells (ECs), increases in response to TNFα. LNK acts as a negative regulator of the pro-inflammatory molecules VCAM-1 and E-selectin induced by TNFα, modulation of P13-kinase and MAPK ERK1/2 activity. LNK is also involved in the negative regulation of Thrombopoietin-mediated cell proliferation and endomitosis in hematopoietic cell lines.

Storage Information

This product is shipped at ambient temperature. It is recommended to aliquot and store at -20°C on receipt. When thawed, aliquot the sample as needed. Keep aliquots at 2-8°C for short term use (up to 4 weeks) and store the remaining aliquots at -20°C.

Avoid repeated freezing and thawing as this may denature the antibody. Storage in frost-free freezers is not recommended.

Where this product has not been tested for use in a particular technique this does not necessarily exclude its use in such procedures. Suggested working dilutions are given as a guide only. It is recommended that the user titrates the product for use in their own system using appropriate negative/positive controls.
Western Blotting
Goat anti Human LNK antibody, directed against the N-teend of the molecule, detects a band of approximately 70 kDa in human MOLT4 cell lysates. (Predicted Mwt. 63.2 kDa). A band of 68 kDA was resolved in HUVECs (Fitau et al. 2006).

Suitable antibodies for loading controls include :

Human anti Human actin β, HCA147 or Rat anti tubulin α,MCA77G.
