Goat anti Human C3d

Goat anti Human C3d

• Background: Tested in immunoelectrophoresis and double radial immunodiffusion against normal Human serum, a single precipitin line is obtained and giving a reaction of full identity with the purified immunogen. The antiserum is also reacting with fragments bearing common determinants: C3, C3b, C3bi. The product does not react with any other proteins component of Human serum or plasma. In supernatants of sera containing 10% polyethyleneglycol only a reaction with C3d has been obtained. In precipitating techniques as immunoelectrophoresis and single and double radial immunodiffusion (Mancini, Ouchterlony) to identify the presence of complement C3d 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. Determinations of individual complement components can be very useful in defining the exact location of a defect.
• CAS Number: 9007-83-4
• UniProt: P01024
• Host: Goat
• Clone: Polyclonal
• Source: C3d is a component of complement. Cell-bound C3b may undergo limited proteolysis to release the fragment C3c and retain C3d on the membrane. The protein is isolated and purified from pooled normal Human serum by precipitation techniques, followed by chromatographical methods. Freund’s complete adjuvant is used in the first step of the immunization procedure.
• Assay Principle: Precipitation assays. In immunoelectrophoresis 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. In single radial immunodiffusion use 1 percent antiserum in the gel.
• Form: Delipidated, heat inactivated, lyophilized, stable whole serum; No preservative added; Total protein and IgG concentrations in the antiserum are comparable to those of; Normal pooled goat serum; No foreign proteins added; Reconstitute the lyophilized antiserum by adding 1 mL sterile distilled water
• Precautions: This product is intended FOR RESEARCH USE ONLY, and FOR TESTS IN VITRO, not for use in diagnostic or therapeutic procedures involving Humans or animals. This datasheet is as accurate as reasonably achievable, but Nordic-MUbio accepts no liability for any inaccuracies or omissions in this information.
• Storage Conditions: The lyophilized antiserum is shipped at ambient temperature and may be stored at +4°C; prolonged storage at or below -20°C; 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
