Immunostaining method, sample exchange chamber, and charged particle beam apparatus

Abstract

In order to enable use of novel immunostaining for a pathological diagnosis and research, the invention provides a sample exchange chamber including: a container 2 into which a substrate on which a sample is placed can be introduced; a specific solution inlet 3, which is a staining mechanism that stains the sample; a cleaning liquid inlet 4, which is a cleaning mechanism that cleans the sample; an evacuation port 5, which is an evacuation mechanism that evacuates the container; a drain port 6; and a sterilization mechanism 7 that sterilizes the sample and inside of the container.
