Ficin Rabbit Polyclonal Antibody

Specifications

Product Data
Applications	ELISA, ID, IF, IP, R, WB
Recommend Dilution	This product is intended for use in precipitating and non-precipitating antibody-binding assays (such as e.g., ELISA and Western blotting and Immunofluorescence or Histochemical techniques). Recommended Dilutions: Non-precipitating antibody-binding techniques: At least 1/1,000.
Host	Rabbit
Clonality	Polyclonal
Immunogen	Ficin isolated and purified from fig tree latex. Freund’s complete adjuvant is used in the first step of the immunization procedure
Specificity	This polyclonal antibody is an immunologic reagents to Ficin from fig tree latex. The reagents were evaluated for potency, purity and specificity using most or all of the following techniques: Immunoelectrophoresis, Cross-Immunoelectrophoresis, single Radial Immunodiffusion (Ouchterlony), block titration, ELISA, Immunoblotting and Enzyme Inhibition. Cross-reactivities against enzymes of other sources may occur but have not been determined.
Formulation	PBS, pH 7.2 without preservatives and foreign proteins Label: Biotin State: Lyophilized hyperimmune IgG fraction Molar radio: Biotin/IgG ~ 6.0
Reconstitution Method	Restore by adding 1.0 ml of sterile distilled water
Concentration	lot specific
Purification	Ammonium Sulphate Precipitation and Ion Exchange Chromatography
Conjugation	Biotin
Storage Condition	Store the antibody lyophilized at 2-8°C and reconstituted at 2-8°C for one week or (in aliquots) at -20°C for longer. If a slight precipitation occurs upon storage, this should be removed by centrifugation.
Background	Ficin is classified as a Thiol Protease. It contains a single reactive Cysteine at its active site. The amino acid homology of the active site is similar to that of Papain. Ficin will cleave proteins at the carboxyl side of Gly, Ser, Thr, Met, Lys, Arg, Tyr, Ala, Asn, and Val. The reported Km for the chromogenic substrate pGlu-Phe-Leu-p-nitroanilide is 0.43 mM. (3) Ficin is inhibited by Iodoacetamide, Iodoacetic Acid, N-Ethylmaleimide, Mercuric Chloride, DFP (diisopropyl fluorophosphate), TLCK (N-alpha-p-Tosyl-lysine Chloromethyl ketone), and TPCK (N-Tosyl-L-Phenylalanine Chloromethyl Ketone). (1,2) Enzyme Commission (EC) Number: 3.4.22.3 Molecular Weight: 23.8 kDa (1). Extinction Coefficient: E1% = 21.0 (280 nm) (2)
