The reactivity of the antiserum is directed to the major isotypes of the mouse immunoglobulin system (classes and both light chain types) including antibodies to common determinants, to class and to the surface determinants of the common Fab portion, as tested by immunoelectrophoresis and double radial immunodiffusion against pooled serum and purified immunoglobulins. In immunoelectrophoresis and double radial immunodiffusion using various antiserum concentrations against normal mouse plasma and serum, the characteristic IgG, IgA and IgM precipitin lines are obtained.
产品特性
Tetramethylrhodamine isothiocyanate-conjugated IgG fraction of polyclonal rabbit antiserum to mouse IgG, IgA and IgM, heavy and light chains, adsorbed for human cross-reactivity. Fluorochrome/IgG protein molar ratio (F/P) is approximately 3.2.
纯化方法
Preadsorption: Immunoaffinity adsorbed using insolubilized Ig-depleted mouse.
免疫原
Purified polyclonal mouse IgG, and homogenous IgA and IgM isolated from mouse serum. Freund's complete adjuvant is used in the first step of the immunization procedure.
Direct immunofluorescence staining of cytoplasmic Ig of appropriately treated cell and tissue substrates, to demonstrate immunoglobulins or specific antibodies in cells and tissues, to identify circulating antibodies in serodiagnostic microbiology and autoimmune diseases, to identify a specific antigen or immune complex using a reference antibody of mouse origin in the middle layer of the indirect test procedure. This immunoconjugate is not pre-diluted. The optimum working dilution of each conjugate should be established by titration before being used. Excess labelled antibody must be avoided because it may cause high unspecific background staining and interfere with the specific signal. Working dilutions are usually between 1:10 and 1:40.

状态
Lyophilized
溶解方式
It is reconstituted by adding 1 mL sterile distilled water. Spun down to remove insoluble particles, divided into small aliquots, frozen and stored at or below -24 °C.
浓度
10 mg/mL
缓冲液
TRITC-coupled purified hyperimmune rabbit IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2).
储存液
Without preservative
注意事项
Prior to use, an aliquot is thawed slowly in the dark at ambient temperature, spun down again and used to prepare working dilutions by adding sterile phosphate buffered saline (PBS, pH 7. 2). Repeated thawing and freezing should be avoided. Working dilutions should be stored at +4 °C, not refrozen, and preferably used the same day. If a slight precipitation occurs upon storage, this should be removed by centrifugation. It will not affect the performance of the immunoconjugate.
储存条件
4 °C/-20 °C
储存方法
The lyophilized conjugate is shipped at ambient temperature and may be stored at +4 °C, prolonged storage at or below -24 °C.
