TRP2 Antibody (C-9) is a mouse monoclonal IgG2a kappa light chain antibody that detects TRP2 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). TRP2 (C-9) antibody is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. TRP2, also known as dopachrome tautomerase, plays a crucial role in the melanin biosynthesis pathway, which is essential for pigmentation in vertebrates. Located in the melanosomal membrane of melanocytes, TRP2 is involved in the enzymatic conversion of dopachrome to 5,6-dihydroxyindole, a key step in the production of eumelanin and pheomelanin. This process is vital not only for the coloration of skin, hair, and eyes but also for protecting against UV radiation. Deficiencies in TRP2 can lead to pigmentation disorders, highlighting its importance in maintaining normal pigmentation and overall skin health. TRP2 interacts with other tyrosinase-related proteins, such as TRP1 and tyrosinase, forming a multi-enzyme complex that enhances the efficiency of melanin production. Using anti-TRP2 antibody (C-9) in research can provide valuable insights into the mechanisms of pigmentation and the molecular interactions that govern melanin synthesis.

We have bought TRP2/DCT Antibody (C-9) FITC. I want to stain the B16 melanoma cells with this antibody and measure with FACS. My question is whether I should stain the cells extracellularly(surface)or intracellularly(after fixation,permeabilization)?

Asked by: atrighods
Thank you for your question. TRP2/DCT Antibody (C-9): sc-74439 is specific against amino acid sequence 41-190 of TRP2 of human origin. This sequence corresponds to lumenal location within melanosomes and would require permeabilization for flow cytometry experiments.
