- Extra Details:
- Lat is an adapter protein expressed in lymphoid cells, which is a substrate for ZAP70 and Syk protein kinases. Phosphorylated LAT associates with GRB2, PLC-gamma1 and P85 PI 3-K. Expression of a mutant LAT protein missing tyrosine phosphorylation sites leads to inhibition of T-cell activation, suggesting that the protein is an important signal transducer in T-cells Applications: Suitable for use in Western Blot and Immunoprecipitation. Other applications have not been tested. Recommended Dilutions: Western Blot: 2-4ug/ml detects LAT in RIPA lysates from Jurkat cells. Jurkat cell lysate was resolved by electrophoresis, transfered to PVDF and probed with L1390 (2ug/ml). Proteins were visualized using IgG (HRP) goat anti-rabbit secondary antibody and a chemiluminescence detection system. Immunoprecipitation: 8-10ug immunoprecipitated LAT from 500ug of Jurkat RIPA lysate Optimal dilutions to be determined by the researcher. Included Positive Antigen Control: J9000: Jurkat lysate. Add 2.5ul of 2-mercaptoethanol/100ul of lysate and boil for 5 minutes to reduce the preparation. Load 20ug of reduced lysate per lane for minigels. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
