Scientific Background
Human linker for activation of T cells family member 1 (LAT), also known as 36 kDa phospho-tyrosine adapter protein, pp36. GenBank Accession No. NM_001014989* variant 4, a.a. 64-269(end), with N-terminal His-tag, expressed in an E. coli expression system. MW = 24.4 kDa. This protein runs at a higher MW by SDSPAGE due to glycosylation.
Product Description
E. coli ExpressionRecombinant LAT Human protein is produced using a validated E. coli expression system and supplied in aqueous buffer solution. Suitable for enzyme kinetics, inhibitor screening, binding assays, structural studies, and related biochemical research applications.

Safety & Handling
Avoid freeze/thaw cycles. Protein may be diluted to ≥100 µg/ml in PBS + glycerol and stored at -80°C.
This protein was produced in E. coli. Expression system selection determines post-translational processing, disulfide bond formation, and co-factor incorporation — all of which affect enzymatic activity. Insect cell (Sf9) systems are preferred for kinases and multi-subunit enzymes that require phosphorylation or chaperone assistance; E. coli is used for structurally simpler proteins.
This protein spans amino acids 64-269(end). Confirm the region includes your domain of interest — the active site, binding pocket, or substrate recognition sequence — before placing your order. Refer to the UniProt database for domain annotation.
Purity is assessed by SDS-PAGE; see the Certificate of Analysis. A gel image is provided with each lot. BPS Bioscience performs rigorous QC on each lot, including purity assessment and functional activity testing where applicable. Contact technical support if purity ≥99% is required for biophysical measurements.
Useful as a kinase substrate and for screening small molecules and antibodies. Refer to the product datasheet for validated protocols and recommended assay conditions. Contact BioHippo technical support for application-specific guidance.
At least 6 months at -80°C. Avoid repeated freeze-thaw cycles — prepare single-use working aliquots. Add BSA or glycerol to aliquots if storing diluted enzyme is necessary. Typical stability is at least 6 months at −80°C.
