C2 Rabbit Polyclonal Antibody

Specifications

Product Data
Applications	ID, IP
Recommend Dilution	Can be used in precipitating techniques as immunoelectrophoresis and single and double radial immunodiffusion (Mancini, Ouchterlony) to identify the presence of C2 or to determine its concentration. The presence of non-precipitating antibodies has not been assayed. This does not exclude the use of the antiserum in non-precipitating antibody-binding techniques if proper controls are included. Directions for use: In immunoelectrophoresis in agarose-plates use 2 μl human plasma or equivalent against 120 μl antiserum. In double radial immunodiffusion use a rosette arrangement with 10 μl antiserum in 3 mm diameter center well and 2 μl plasma samples (neat and serially diluted) in 2 mm diameter peripheral wells.
Reactivity	Human
Host	Rabbit
Clonality	Polyclonal
Immunogen	The C2 component of human complement is a single-chain polypeptide with a molecular weight of 110,000. It is present in plasma in an average concentration of 25 μg/ml. The activated form of C2 combines with the activated C4 to form a complex with C3-convertase activity in the classical pathway of complement activation. C2 is isolated as a homogenous protein for use in the antiserum production. Freund’s complete adjuvant is used in the first step of the immunization procedure.
Specificity	The reactivity of the antiserum is restricted to native and activated C2. In immunoelectrophoresis and radial immunodiffusion, using various antiserum concentrations against human plasma a single precipitin line is obtained and shows a reaction of full identity with the purified immunogen. Cross-reactivity: The antiserum does not cross-react with any other human plasma proteins as tested in geldiffusion techniques. Inter-species cross-reactivity is a normal feature of antibodies to plasma proteins, since homologous proteins of different species frequently share antigenic determinants. Cross-reactivity of this antiserum has not been tested in detail.
Formulation	No preservative added - No foreign proteins added. State: Serum State: Delipidated, heat inactivated, lyophilized, stable IgG fraction
Reconstitution Method	Restore with 1 ml sterile distilled water.
Concentration	lot specific
Conjugation	Unconjugated
Storage Condition	Prior to reconstitution store at 2-8°C. Following reconstitution store undiluted at 2-8°C for one week or (in aliquots) at -20°C for longer. Avoid repeated freezing and thawing.
Gene Name	complement component 2
Database Link	Entrez Gene 717 Human UniProt ID P06681
Synonyms	C2, C3/C5 convertase
Note	Adsorption: Immunoaffinity adsorbed using insolubilized antigens as required, to eliminate antibodies reacting with other human serum proteins. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.

Protein Families	Druggable Genome, Protease, Secreted Protein
Protein Pathways	Complement and coagulation cascades, Systemic lupus erythematosus
