如题，我是学化学的，我看有文献是这样写的。固定生物介质不应该是通过共价或非公价相互作用吗？谢谢 Firstly, 50 μL of the Ab1 solution (10 μg/mL) was added into pre-defined wells of the 96-well PS plate and the plate was incubated at 4 °C overnight. After discarding the solutions, the plate was washed by PBS buffer. Next, the plate was blocked with 1% BSA (50 μL) at room temperature for 1.5 h and rinsed with PBS solutions for three times.
