CHO細胞 ELISA 試劑盒的英文描述
The antibodies used in the kit were generated against and affinity purified from a cell lysate of CHO cells grown in serum supplemented media. All three of the Cygnus CHO HCP kits recognize a qualitatively vast majority of the same HCPs. The potential exists that the quantitative value reported for a given sample type may differ between the kits, therefore we cannot predict which kit will be most suitable for your applications. Formal qualification must be performed on each different product, to determine which of the 3 kits are superior. For labs looking at CHO HCP contamination for the first time, we suggest evaluating our CHO HCP ELISA, 3G, Catalog # F550. If this method proves inadequate then we suggest evaluating CHO HCP kits, Catalog #CM015 and F015.

CHO ELISA kit 的使用步驟規(guī)則
The CHO Host Cell Protein assay is a two-site immunoenzymetric assay. Samples which may contain CHO proteins are reacted with an affinity purified alkaline phosphatase labeled antibody. This reaction either takes place in a test tube in a sequential assay mode or simultaneously in microtiter wells coated with an anti-CHO HCP capture antibody.The two-step sequential protocol or the one step simultaneous
protocol result in the formation of a sandwich complex of solid phase (capture) antibody-CHO protein-enzyme labeled antibody. The microtiter strips are then washed to remove any unbound reactants. The substrate p-nitrophenyl phosphate (PNPP) is then reacted. The amount of hydrolyzed substrate is read on a microtiter plate reader and will be directly proportional to the concentration of CHO proteins present.

CHO ELISA kit 的保存和穩(wěn)定性
* All reagents should be stored at 2°C to 8°C for stability until the expiration date printed.
* The substrate reagent should not be used if its absorbance at 405nm is greater than 0.4.
* Reconstituted wash solution is stable until the expiration date of the kit.
