Sheep anti Mouse IgG2a (1b allotype specific)

The reactivity of the antiserum is restricted to the Fc portion of the IgG2a molecule. In immunoelectrophoresis and radial immunodiffusion, using various antiserum concentrations against mouse serum of the allelic type Igh-1b, including C57Bl and SJL/J, a single characteristic precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified IgG2a(1b). No precipitation reaction is obtained with purified IgG2a(1a) (Balb/C, CBA, AKR and NZB), other IgG subclasses, IgA, IgG/Fab fragments or other serum proteins. In precipitating techniques as immunoelectrophoresis and radial immunodiffusion to identify the presence of IgG2a(1b) in mouse serum and other body fluids or to determine its concentration. To prepare an immunoadsorbent for the purification of mouse IgG2a(1b) from serum or plasma. This antiserum is not intended for use in non-precipitating antibody-binding or other highly sensitive assays. For such use labelled an unlabelled cytochemical and immunoassay grade reagents meeting the necessary additional specificity an performance requirements are available.

Highly purified normal homogenous IgG2a(1b) isolated from mouse serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.

Delipidated, heat inactivated, lyophilized, stable whole antiserum; No preservative added; Total protein and IgG concentrations in the antiserum are comparable to those of pooled; Normal sheep serum; No foreign proteins added._x000D_ Reconstitute the lyophilized antiserum by adding 1 mL sterile distilled water

This datasheet is as accurate as reasonably achievable, but Nordic-MUbio accepts no liability for any inaccuracies or omissions in this information.

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
