12. Hold the salivary glands at the common duct with tweezers.Transfer the glands to a drop of fixing solution on a siliconizedcoverslip. 13. Incubate the glands for 10-20 min, occasionally stirring with the tip of the tweezers to ensure homogeneous fixation. The fixation time is an important parameter and needs to be adjusted for every antigen tested. Aim for the sho......阅读全文
