Platelet factor 4 polyclonal, anti-human

Quantity: 200 µl

Background:
The reactivity of the antiserum is restricted to platelet factor 4 as tested in immunoelectrophoresis and radial immunodiffusion. A characteristic single precipitin line is obtained with normal serum which shows a reaction of identity with the precipitin line with purified immunogen. In precipitating techniques as electroimmunodiffusion (Laurell), immunoelectrophoresis and single and double radial immunodiffusion to identify the presence platelet factor 4. This antiserum has not been tested in more sensitive assays as nephelometry, ELISA or use in immunohistology, but this does not exclude such use if proper controls are included. Measurement of platelet factor 4 is of significance for diagnosis of platelet disorders involving platelet alpha granules and to demonstrate increased platelet secretion in vivo. Reduced levels are measured in gray platelet syndrome, whereas elevated levels have been reported in cases as coronary artery disease, myocardial infarction, disseminated intravascular coagulation, cerebrovascular disease and cancer.

Isotype: Rabbit Polyclonal

Source: Platelet factor 4 is a low molecular weight (MW 7,800) heat stable protein, secreted by alpha granules of the platelets. Purified platelet factor 4 isolated from pooled human serum. Freund's complete adjuvant is used in the first step of the immunization procedure.

Form: Delipidated, heat inactivated, in PBS and 0.1% sodium azide.

Reactivity: human

Cross Reactivity:
Inter-species cross-reactivity is a normal feature of antibodies to Serum proteins, since homologous proteins of different species frequently share antigenic determinants. Crossreactivity of this antiserum has not been tested in detail. In double radial immunodiffusion a reaction has been observed with Bovine, Cat, Dog and Monkey.

Applications: Immunoprecipitation

Storage: Store at 4C, or in small aliquots at -20C.
