Format: 1mg/ml in Phosphate Buffered Saline (PBS), 0.09% sodium azide.
BACKGROUND
Enterokinase, also known as enteropeptidase, is a serine protease that catalyzes the hydrolysis of peptide bonds in proteins but, unlike other kinases, does not catalyze transfer of phosphate groups. Enterokinase cleaves proteins following a lysine at an enterokinase cleavage site, or ECS (Asp-Asp-Asp-Asp-Lys). In vivo, this cleavage results in trypsin-dependent activation of other pancreatic zymogens, such as chymotrypsinogen, proelastase, procarboxypeptidase and prolipase in the lumen of the gut.
SPECIFICATION SUMMARY
Antigen: DDDDK conjugated to KLH.
Host Species: Rabbit
Specificity: Antibody was affinity-purified on the peptide.
APPLICATIONS
Immunoblotting: use at a dilution of 1:1,000- 1:20,000.
Immunocytochemistry: use at a dilution of 1:100-1:400.
Immunoprecipitation: use 1-4ug/mg lysate. ELISA: for detection use at a dilution of 1:1,000-1:30,000; for coating use at a dilution of 1:100-1:500.
These are recommended dilutions. Endusers should determine optimal dilutions for their applications.
Detection of ECS-tagged protein in 200, 100, and 50ng of E. coli lysate containing tagged fusion protein with #18832 diluted 1:25,000.
DILUTION INSTRUCTIONS
