vivoPharm offers immunohistchemistry, detection of antigens and detection of target molecules in tumours. Our library of human tumours grown subcutaneously or orthotopically and embedded either in OCT or paraffin is ideal for many immunohistochemical studies. vivoPharm has many years of experience in optimising antigen detection in tissue sections and has systems available to detect human cells in a mouse background, which is especially of interest for metastases or leukemia models.
