The reactivity of the antiserum is directed to the Fc subunit of subclass IgG2.
产品特性
Total protein and IgG concentration in the antiserum are comparable to those of pooled normal rabbit serum. Antibody titre: Precipitin titre not less then 1:32 when tested against pooled normal guinea pig serum in agar block imm
纯化方法
Delipidated, heat inactivated, lyophilized whole antiserum. Immunoaffinity adsorbed using insolubilized antigens as required to eliminate antibodies cross-reacting with other components of the immunoglobulin system or reacting with other serum proteins. Special attention is given to the removal of antibodies to common Ig/Fab. The use of insolubilized adsorption antigens prevents the presence of excess adsorbent protein or immune complexes in the antiserum.
免疫原
Pools of purified normal IgG2 isolated from pooled guinea pig serum. Freund's complete adjuvant is used in the first step of the immunization procedure.
In precipitating techniques as immunoelectrophoresis and radial immunodiffusion to identify the presence of IgG2 in guinea pig serum and other body fluids or to determine its concen-tration. To prepare an immunoadsorbent for the purification of guinea pig IgG2 from serum or plasma.

状态
Lyophilized
溶解方式
Reconstitute the lyophilized antiserum by adding 1 mL sterile distilled water.
缓冲液
No foreign proteins added.
储存液
Without preservative
注意事项
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 pre ferably used the same day.
储存条件
4 °C/-20 °C
储存方法
The lyophilized antiserum is shipped at ambient temperature and may be stored at +4 °C, prolonged storage at or below -24 °C.
