Prekallikrein antibody

Catalog No. ABIN458043

Product Details anti-Prekallikrein Antibody

Target: Prekallikrein (PK)

Reactivity: Human

Host: Goat

Clonality: Polyclonal

Conjugate: This Prekallikrein antibody is un-conjugated

Application: Immunoelectrophoresis (IEP), Immunodiffusion (ID)

Specificity: The antiserum does not cross-react with any other human plasma proteins as tested in gel-diffusion techniques. Inter-species cross-reactivity is a normal feature of antibodies to plasma proteins, since homologous proteins of different species frequently share antigenic determinants. of this antiserum has not been tested in detail, however in double radial immunodiffusion a reaction with monkey has been observed.

Characteristics: Precipitating polyclonal goat antiserum to human prekallikrein

Purification: 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.

Immunogen: Prekallikrein is a single-chain. Glycoprotein (MW 88,000) present in inactive form in plasma, pancreas and intestine. Prekallikrein is activated to kallikrein by Factor XIIa which in turn results from activation of Factor XII by prekallikrein combined with Factor XII and high-molecular-weight kininogen (HMWK). It releases kinins from the low-molecular-weight and the high-molecular-weight kininogen. Highly purified molecular weight kininogen isolated from pooled plasma. Freund’s complete adjuvant is used in the first step of the immunization procedure.

Isotype: IgG

Application Details

Application Notes: As precipitating antiserum in electroimmunodiffusion, immunoelectrophoresis and radial immunodiffusion. This does not exclude the use of the antiserum in more sensitive techniques if proper controls are included.

Restrictions: For Research Use only

Handling

Format: Lyophilized

Concentration: Total protein and IgG concentration in the antiserum are comparable to those of pooled normal goat serum. No foreign proteins added. Antibody titre: Precipitin titre not less than 1:32 when tested against normal human plasma in agar block immunodiffusion

Buffer: Delipidated, heat inactivated, lyophilized, stable whole serum.

Preservative: Without preservative

Storage: 4 °C/-20 °C

Storage Comment: The lyophilized antiserum is shipped at ambient temperature and may be stored at +4°C, prolonged storage at or below -20°C. Reconstitute the lyophilized antiserum by adding 1 ml sterile distilled water. Dilutions may be prepared by adding phosphate buffered saline (PBS, pH 7.2). Repeated thawing and freezing should be avoided. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the antiserum. Diluted antiserum should be stored at +4°C, not refrozen, and preferably used the same day.

Alternative Name: Prekallikrein (PK Products)

Synonyms: APS antibody, KLK2A1 antibody, PSA antibody, hK3 antibody, kallikrein related peptidase 3 antibody, KLK3 antibody

Background: The defined antibody specificity is to prekallikrein. Plasma kallikrein is present in two slightly different forms. This corresponds with two different forms of kallikrein after prekallikrein has been activated by Factor XIIa. Inactive plasma prekallikrein and active kallikrein may react with the antiserum. Although prekallikrein exhibits structural homology to Factor XI, the antiserum does not react with Factor XI
