Product Info
Background S-tag is an epitope tag composed of a 15 residue peptide, KETAAAKFERQHMDS, derived from the pancreatic ribonuclease A. Frederick Richards discovered the S-peptide/S-protein system. Ribonuclease A is split by enzyme subtilisin between amino acids 20 and 21 yielding ribonuclease S. Ribonuclease S is composed of the peptide corresponding to the first 20 amino acids, S-peptide, attached to the remainding amino acids 21-124, S-protein. Ribonuclease S has the full enzymatic activity of the parent protein and the two components, S-peptide and S-protein could be separated by reversible denaturation. The separation abolished enzymatic activity, but when the two components were mixed together again, fully active ribonuclease S is formed. The unique property of reconstituting enzymatic activity by the S-tag peptide:S-protein interaction enables sensitive quantitative measurement of any fusion protein by a simple assay. 
Form S-tag (E15)+FITC is provided as an affinity purified rabbit polyclonal antibody conjugated to HRP, raised against a peptide derived from the pancreatic ribonuclease A. 
Product Details Each vial contains 200 g in 0.2ml of affinity purified rabbit IgG, S-tag (E15)+FITC DB117, in a buffer containing 50mM HEPES pH 7.0, 0.1 M soduim chloride, 0.2% BSA and 0.01 % Thimerosal and 0.2% gelatin. 
Immunogen Synthetic peptide, KETAAAKFERQHMDS, derived from the pancreatic ribonuclease A.
