Cobioer Gene provides combined positive and negative TF (Tissue Factor) IHC controls in two formats: FFPE tissue blocks and pre-cut FFPE control slides. The controls are validated by immunohistochemistry for routine quality control of TF IHC assays and companion diagnostic assay development. For Research Use Only. Read More

The format of an IHC control can influence how easily a laboratory develops, validates, and monitors a PSMA staining workflow. While both paraffin blocks and pre-cut slides can be used as FFPE control materials, they support different laboratory needs. Read More

Reliable immunohistochemistry depends on more than selecting an antibody against the correct target. Laboratories also need appropriate control materials to evaluate whether the staining result is specific, interpretable, and reproducible. Read More

Prostate-specific membrane antigen, commonly known as PSMA, has become an important biomarker in prostate cancer research, pathology, and targeted diagnostic development. Read More

HLA genotyping assays require careful validation because the HLA system contains a large number of highly polymorphic alleles. Read More

HLA typing results often appear as combinations of letters, numbers, colons, and suffixes. For laboratories developing or evaluating HLA assays, understanding this format is essential. A result such as HLA-B*15:02 is not an arbitrary code. Read More
