[0022] Example Preparation of Immunoaffinity Column for Rapid Purification and Enrichment of Cimaterol

[0023] 1. The cimaterol is diazotized by the diazo method and then coupled to the carrier protein to obtain an immunogen, and the immunogen is immunized with animals to produce antiserum; the specific steps are as follows:

[0024] (1) Preparation of cimaterol immunogen

[0025] ① Weigh 10mg of cimaterol standard, dissolve in 100uL tetrahydrofuran, add 900μL 1mol / L HCl, freeze for 5 minutes; add 50mg solid sodium nitrite, shake well after freezing for 2 minutes, continue to react at 4°C for 30 minutes, and obtain the weight Nitrided cimatero;

[0026] ②Weigh 100mg of bovine serum albumin and dissolve it in 5mL0.1mol / LNa 2 CO 3 , freeze for 2 minutes and then add 0.5 mL of saturated Na 2 CO 3 ;

[0027] ③ Add the cimaterol obtained in step ① to the bovine serum albumin solution in step ② and react overnight on a shaker at room temperature; desalt with SephadexG25 to o

Abstract

The invention discloses an immunoaffinity column for quickly purifying and enriching cimaterol. The immunoaffinity column is obtained by loading cimaterol-resistant immunoaffinity filler into an empty column tube; the cimaterol-resistant immunoaffinity filler consists of a solid phase carrier and a cimaterol specificity polyclonal antibody coupled with the solid phase carrier; the cimaterol specificity polyclonal antibody is obtained by preparing antiserum through a conjugate which is obtained by coupling the cimaterol diazotized by a diazotizing method with a carrier protein and then purifying the antiserum by an immunoaffinity method. The invention also discloses a preparation method and application of the immunoaffinity column. The specificity of the antibody used by the immunoaffinity column disclosed by the invention is high; the immunoaffinity column disclosed by the invention is used for pretreating a sample; then the immunoaffinity column is used after being combined with a chromatographic method and a colloidal gold test strip, so that the content of the cimaterol can be efficiently and accurately detected.
