The Rabbit Polyclonal anti-Complement C3b antibody is suitable to detect Complement C3b in samples from Human. It has been validated for IEP and RID.

Quick Overview for Complement C3b antibody (ABIN458141)

Target: Complement C3b (C3b) (Complement C3 beta Chain (C3b))

Reactivity: Human

Host: Rabbit

Clonality: Polyclonal

Conjugate: This Complement C3b antibody is un-conjugated

Application: Immunoelectrophoresis (IEP), Radial Immunodiffusion (RID)

Product Details anti-Complement C3b Antibody

Purpose: Rabbit anti Human C3b

Specificity: Precipitin titre not less than 1:16 when tested anti normal Human plasma in agar-block immunodiffusion titRation.

Cross-Reactivity (Details): Inter-species cross-reactivity is a normal feature of antibodies to plasma proteins, since homologous proteins of different species frequently share antigenic determinants. Crossreactivity of this antiSerum has not been tested in detail.

Characteristics: In immunoelectrophoresis and radial immunodiffusion, using various antiserum concentrations against human plasma a single precipitin line is obtained in the beta-1 region and shows a reaction of full identity with the purified immunogen. The antiserum does not react with any other protein component of human serum or plasma. In precipitating techniques as immunoelectrophoresis and single and double radial immunodiffusion (Mancini, Ouchterlony) to identify the presence of complement C3b 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.

Purification: Delipidated, heat inactivated, lyophilized, stable whole antiserum

Immunogen: C3b (C3c+C3d) has a molecular weight of 170,000. 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.

Isotype: IgG

Application Details

Application Notes: 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.

Restrictions: For Research Use only

Handling

Format: Lyophilized

Reconstitution: Reconstitute the lyophilized antiserum by adding 1 mL sterile distilled water.

Buffer: 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 rabbit serum. No foreign proteins added.

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. 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.
