Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B IP
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
Catalog #L1390
ApplicationsSuitable for use in Western Blot and Immunoprecipitation. Other applications have not been tested.
Recommended DilutionsWestern 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 ControlJ9000: 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.
