Properdin polyclonal FITC, anti-human

Quantity: 200 µl

Background:
In immunoelectrophoresis against human serum a single precipitin line is obtained. The antiserum does not react with any other protein component of human serum or plasma. As reagent for the direct detection of properdin in human cells, tissues and body fluids in immunofluorescence; as detection reagent in non-isotopic methodology and solid phase immunochemistry (e.g. ELISA).This immunoconjugate is not pre-diluted. The optimum working dilution of each conjugate should be established by titration before being used. Excess labelled antibody must be avoided because it may cause high unspecific background staining and interfere with the specific signal.Working dilutions are usually between 1:10 and 1:60.

Isotype: Goat Polyclonal

Source: Properdin is a factor of the alternative complement activation pathway. It has a molecular weight of 222,000 and consists of four peptide chains. Properdin is stabilizing the C3 convertase C3bBb. The mean concentration in plasma is 20 mg/ml. The antigen has been isolated form pooled human plasma. Freund's complete adjuvant is used in the first step of the immunization procedure.

Form: Fluorochrome-coupled purified hyperimmune IgG, in phosphate buffered saline (PBS, pH 7.2)

Specificity:
Fluorescein isothiocyanate-conjugated IgG fraction of polyclonal Goat anti-Serum to Human properdin

Reactivity: human

Cross Reactivity:
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. Cross-reactivity of this antiserum has not been tested in detail.

Applications: ELISA, Immunocytochemistry, Immunohistochemistry (frozen), (In)direct immunofluorescence

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