In enzyme-immunocytochemical and immunohistochemical staining for the detection of IgG2b at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates, to demon-strate circulating IgG2b antibodies in serodiagnostic microbiology and autoimmune diseases, to identify a specific antigen using a reference antibody of rat origin known to be of the IgG2b isotype in the middle layer of the indirect test procedure, in non-isotopic assay methodology (e.g. ELISA) to measure IgG2b in rat serum or other body fluids. 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 for histochemical and cytochemical use are usually between 1:50 and 1:250, in ELISA and comparable non-precipitating antibody-binding assays between 1:1,000 and 1:10,000 depending on the method used.
限制
仅限研究用
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
Peroxidase-coupled purified hyperimmune goat IgG lyophilized from a solution in phosphate buffered saline (PBS, pH 7.2).
储存液
Without preservative
注意事项
Use of Sodium Azide will inhibit enzyme activity of horseradish peroxidase. Prior to use, an aliquot is thawed slowly 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.
