USEOFTHELIGHTMICROSCOPE
USE OF THE LIGHT MICROSCOPEEach time the microscope is to be used it should be set up correctly to give a good image. Most often users forget to adjust the iris diaphragm and focus the condenser to give its optimum performance, this could result in objects in the preparation being undetected.There are many microscope set up procedures for specific functionality but the most versatile for general use is ‘Critical Illu......阅读全文

关于轻链的基本信息介绍
轻链(light chain，L chain)指免疫球蛋白中分子量较小的肽链，含214个氨基酸，根据其结构和恒定区抗原性的差异分为“κ轻链(kappa light chain)”和“λ轻链(lambda light chain)”两种型别。 免疫球蛋白(Ig)的每条轻链由214个氨基酸残基组成
