Product Specific Information
Recombinant rabbit monoclonal antibodies are produced using in vitro expression systems developed by cloning specific antibody DNA sequences from immunoreactive rabbits. Individual clones are screened to select optimal candidates for production.
Advantages:
- Enhanced specificity and sensitivity
- Lot-to-lot consistency
- Animal origin-free formulations
- Broader immunoreactivity due to the rabbit immune repertoire
Target Information
LCK is a member of the Src-family tyrosine kinases essential for T-cell receptor (TCR) signaling. Upon TCR activation, LCK phosphorylates ITAM motifs in the zeta subunits, creating binding sites for the SH2 domains of ZAP70. Activated ZAP70 phosphorylates adaptor LAT, forming signaling platforms for downstream pathways.
Most LCK localizes to the plasma membrane, with a fraction associated with the Golgi apparatus, potentially contributing to Raf activation during weak TCR stimulation. LCK contains N-terminal myristylation and palmitylation sites, a PTK domain, and SH2/SH3 domains that mediate protein-protein interactions. It also regulates apoptosis induced by various stimuli, excluding death receptor-mediated pathways.
Diseases associated with LCK include Immunodeficiency 22 and CD45 deficiency. Alternative splice variants encoding different isoforms have been identified.
