  • Title: Optimized dyeing conditions of immunoprotein with reactive dye Procion Blue MX-7RX.
    Author: Wang SJ, Lin HM, Wang XR, Hsiung KP, Liu YC.
    Journal: Anal Biochem; 2007 Feb 15; 361(2):190-6. PubMed ID: 17196156.
    Abstract:
    For investigating the feasibility of using reactive dyes as an immunoassay marker, a dichlorine triazine dye, Procion Blue MX-7RX, was employed to stain the antibody against human serum albumin (anti-HSA). With the color intensity revealed in the immunochromatographic test strip as the objective variables, the optimal dyeing conditions were found as follows: pH 11.4, temperature 35.7 degrees C, molar ratio 188 (mol dye/mol antibody), and reaction time 45.6 min. The dyed-anti-HSA revealed a maximal color intensity of 8738 without apparent loss of antigen binding affinity.
