• Target description: Tyrosine-protein kinase Lck (UniProt: P06239; also known a EC:2.7.10.2, Leukocyte C-terminal Src kinase, LSK, Lymphocyte cell-specific protein-tyrosine kinase, Protein YT16, Proto-oncogene Lck, T cell-specific protein-tyrosine kinase, p56-LCK) is encoded by the LCK gene (Gene ID: 3932) in human. Lck is a non-receptor tyrosine kinase that is specifically expressed in lymphoid cells. It plays an essential role in the selection and maturation of developing T-cells in the thymus and also plays a role in function of mature T-cells. Its protein kinase domain is localized to amino acids 245-498. It is reported to constitutively associate with the cytoplasmic region of the CD4 and CD8 receptors. It also plays a role in T-cell antigen receptor (TCR)-linked signaling. Association of the TCR with a peptide antigen-bound MHC complex facilitates the interaction of CD4 and CD8 with MHC class II and class I molecules, respectively. This results in recruitment of Lck to the vicinity of the TCR/CD3 complex where Lck can phosphorylate tyrosine residues within the immunoreceptor tyrosine-based activation motifs (ITAM) of the cytoplasmic tails of the TCR- chains and CD3 subunits that initiates the TCR/CD3 signaling. Once stimulated, the TCR recruits the tyrosine kinase ZAP70 that becomes phosphorylated and activated by Lck. Following this, a large number of signaling molecules are recruited, ultimately leading to lymphokine production. Autophosphorylation of Lck on tyrosine 394 increases its enzyme activity, whereas phosphorylation on tyrosine 505 by C-terminal Src kinase (CSK) results in a reduction in its activity. This ZooMAbZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

• Physical form: Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
• Reconstitution: 30 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.
• Storage and Stability: Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
