As unlabelled primary or secondary reagent for indirect detection of IgG2a at the cellular and subcellular level by staining of appropriately treated cell and tissue substrates, to prepare conjugates of the user's own choice, to prepare an insoluble immunoaffinity adsorbent or a solid phase antibody reagent by coupling to an artificial carrier and as catching antibody in non-isotopic methodology and solid phase immunochemistry. When applied in any cytochemical or histochemical staining procedure or solid phase coupling technique, the optimum concentration of the IgG preparation should be established by titration before being used. Typical working dilutions in histochemistry are usually between 1:100 and 1:500, in ELISA and comparable non-precipitating antibody-binding assays between 1:500 and 1:5,000.

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
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
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 product.
储存条件
4 °C/-20 °C
储存方法
The lyophilized IgG (7S) fraction is shipped at ambient temperature and may be stored at +4 °C, prolonged storage at or below -24 °C.
