COMMENT
How to submit lung cancer PD-L1 protein (IHC) 22C3
1) Since the presence or absence of cancer cells may be unknown, please attach a copy of the pathological diagnosis when requesting the test. (However, it is not necessary if our company conducts general pathological examinations.) If it is not possible to attach it for various reasons, please include the name of the pathological diagnosis (tissue type, etc.) in the request form, as well as clinical information to the extent possible. Please fill in the form below.
2) The material is an unstained specimen slide (made from a formalin-fixed paraffin block) of lung cancer (primary tumor or metastatic tumor). Please use slides coated with silane, etc., and after slicing, dry overnight at approximately 40℃ before submitting.
3) Slice the tissue to a thickness of 4 to 5 μm and attach it as close to the center as possible, keeping it at least 15 mm from the edge of the frost and at least 15 mm from the edge of the glass slide.
4) If you request paraffin blocks, there will be a delay in the number of days required to prepare unstained slides, so please check with our sales staff.
