Pan TRK [RM423]

Product Description

The Biocare Pan TRK [RM423] rabbit monoclonal antibody targets the neurotrophic tyrosine receptor kinase (NTRK) proto-oncogenes. The NTRK proto-oncogenes NTRK1, NTRK2, and NTRK3 (that encode TRK A, TRK B, and TRK C proteins, respectively) may form gene fusions through their kinase domains, driving tumor development.¹⁵ TRK A is activated by nerve growth factor (NGF), TRK B by brain-derived neurotrophic factor (BDNF) or neurotrophin-4 (NT-4), and TRK C by neurotrophin3 (NT-3).¹⁶ NTRK fusions are characteristic of a few rare types of cancer, such as secretory carcinoma of the breast or salivary gland and infantile fibrosarcoma, but they are also infrequently seen in some common cancers, such as melanoma, glioma and carcinomas of the thyroid, lung and colon.^17,18 The Pan TRK immunohistochemical staining may be useful in the aiding of classification of cancers exhibiting NTRK fusions.^17,19
