交叉反应 （详细）
- Inter-species cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. Precipitation reactions have been observed with free and bound secretory component in serum of other old-world Monkeys, including Cercopithecus, Cynomolgus and Baboon. The antiserum may also react with other species as has been observed for Chimpanzee.
-
产品特性
- Secretory IgA (sIgA) functions as a dimer or polymer and accounts for almost all specific mucosal antibody activity. A molecule of sIgA is made up of two molecules of IgA, one J chain and one SC (MW 65,000). The dimer IgA is transported into secretions by its binding to the SC on the epithelial cells. SC also has an affinity for polymeric IgM.

纯化方法
- Delipidated, heat inactivated, lyophilized, stable whole antiserum
-
免疫原
- Purified free secretory component isolated from pooled rhesus monkey milk is used for immunization. Freund's complete adjuvant is used in the first step of the immunization procedure.

亚型
- IgG

应用备注
- Precipitation assays. In immunoelectrophoresis use 2 μL serum or equivalent against 120 μL antiserum. In double radial immunodiffusion use a rosette arrangement with 10 μL antiserum in 3 mm diameter centre well and 2 μL serum samples (neat and serially diluted) in 2 mm diameter peripheral wells. Tested in immunoelectrophoresis, double radial immunodiffusion and ELISA against a panel of appropriate secretions and purified Ig isotypes. The antiserum reacts with both bound secretory component (secretory IgA) and with the free SC present in monkey secretions. In immunoelectrophoresis against monkey milk, using a high electroendosmosis agar plate, free SC is precipitated in the alph-2 region. The antiserum does not react with other molecular forms of IgA, or with any other secretory or plasma protein. In precipitating techniques as immunoelectrophoresis and single and double radial immunodiffusion to identify the presence secretory component in monkey serum or other body fluids and to determine its concentration.

状态
- Lyophilized
-
溶解方式
- Reconstitute the lyophilized antiserum by adding 1 mL sterile distilled water.
-
缓冲液
- 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 goat serum. No foreign proteins added.
-
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 -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.
