To conjugate an antibody to FITC using this kit: - add modifier to antibody and incubate for 3 hrs. - add quencher and incubate for 30 mins. The FITC conjugated antibody can be used immediately in WB, ELISA, IHC etc.
WebThese protocols can serve as a models for the fluorescent conjugation of nearly any protein. No protocol is given for antibody purification after conjugation (e.g., Protein A or Protein G). ... The conjugations fall into four basic protocols: Type 1 (used for FITC, Cy5, and the initial preparation of the Cy5 and Cy7 tandem dyes); Type 2 (used ...
WebC Reactive Protein is a major acute phase reactant synthesized primarily in the liver hepatocytes. It is a pentraxin (cyclic pentameric protein) compound of five identical nonglycosylated subunits of 206 amino acids each (m.w. 24 kDa), that are bound noncovalently to form the physiologic CRP molecule (m.w. 117.5 kDa). high ph numberWebDilution factor = Amount, if any, sample was diluted before absorbance readings were taken. Protein Concentration (M) = ( (A280 - (Amax x CF)) ÷ ε) X Dilution factor. Calculate the degree of labeling: ε' = dye molar extinction coefficient.
