For the cystamine-glutaraldehyde method, the crystal was immersed in a cystamine solution (10 mmol/L cystamine, 50 mmol/L phosphate buffer, 0.
In this experiment, five immobilization methods, including adsorption, protein A, ConA, cystamine-glutaraldehyde, and cystamine, were used to immobilize anti-AFP MAbs on the gold surface of quartz crystals.
3 shows that the reusability of quartz crystals prepared by the cystamine method developed in our laboratory was better than those of the other methods.
We previously directly compared results obtained with these two reducing agents and found that although the use of TCEP produced higher relative fluorescence intensities, the calculated concentrations of plasma tHcy were not significantly different if calibration was performed in plasma and cystamine was used as the internal standard (7).
6), as the reducing agent, cystamine as the internal standard, and isocratic separation of the thiols extracted from only 50 /,L of plasma within 6 min.
The internal standard was cystamine dihydrochloride, which was added to all samples to achieve a final concentration of 10 [micro] mol/L free thiol (in 100-micro] L assay volume).
The use of cystamine as the internal standard significantly improves the precision of this method and overcomes the matrix effect of plasma.
