BackgroundThe reactivity of the antiserum is restricted to the Fc part of the IgM molecule. In immunoelectrophoresis and radial immunodiffusion, using various antiserum concentrations against normal human serum a single precipitin line is obtained which shows a reaction of identity with the precipitin line obtained with purified IgM. No precipitation reaction is obtained with purified IgG, IgA, and IgG/Fab fragments. In precipitating techniques as immunoelectrophoresis and radial immunodiffusion to identify the presence of IgM in human serum and other body fluids or to determine its concentration. To prepare an immunoadsorbent for the purification of human IgM from serum or plasma.

SourceHighly purified normal IgM isolated from pooled human serum. Freund’s complete adjuvant is used in the first step of the immunization procedure.

ProductDelipidated, heat inactivated, lyophilized, stable whole antiserum. No preservative added. Total protein and IgG concentrations in the antiserum are comparable to those of pooled normal swine serum. No foreign proteins added. Reconstitute the lyophilized antiserum by adding 1 ml sterile distilled water.

Formulation: 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 swine serum. No foreign proteins added.

SpecificityPrecipitating polyclonal Swine antiSerum to Human IgM, Fc specific.

Species Reactivity: The antiSerum does not cross-react with any other component of the Human Ig system. Interspecies cross-reactivity is a normal feature of antibodies to immunoglobulins, since Ig of different species frequently share antigenic determinants. In immunoelectrophoresis crossreactivity of this antiSerum has not been observed with Serum of Rhesus Monkey, Cynomolgus and Baboon.

ApplicationsPrecipitation assays. In immunoelectrophoresis use 2 μl or equivalent against 120 μl antiserum. In double radial immunodiffusion (Ouchterlony) use a rosette arrangement with 10 μl in a 3 mm diameter center well and 2 μl serum samples (neat and serially diluted) in 2 mm diameter peripheral wells.

StorageThe 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.

评估细胞周期进程在许多研究领域都非常重要，传统的方法是将[3H]胸腺嘧啶核苷掺入S期细胞，然后通过闪烁计数或放射自显影来定量[3H], 以此来检测细胞增殖，但该技术流程耗时且费力，还有许多限制因素比如同位素污染处理和设备昂贵等问题。
