TMP21 Antibody (A-7) is a mouse monoclonal IgG2a kappa light chain antibody that detects TMP21 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). anti-TMP21 antibody (A-7) 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. TMP21, also known as the 21 kDa transmembrane-trafficking protein or TMED10, is a crucial component of the EMP24/GP25L/p24 cargo family, which plays a significant role in regulating vesicular trafficking within the early secretory pathway. TMP21 is predominantly localized to the Golgi cisternae and the plasma membrane, where TMP21 functions as a single-pass type I membrane protein. A GOLD (Golgi dynamics) domain in TMP21 is essential for involvement in protein transport and quality control between the endoplasmic reticulum and the Golgi complex, ensuring that only properly folded and assembled proteins proceed through the secretory pathway. TMP21 is a vital component of the heteromeric secretase complex, also known as the Presenilin complex, where TMP21 modulates γ-secretase activity, a process that is critical for the regulation of various signaling pathways and maintenance of cellular homeostasis. Two isoforms, TMP21-I and TMP21-II, further highlight the complexity and functional diversity of TMP21, making TMP21 (A-7) monoclonal antibody an invaluable tool for researchers studying protein trafficking and processing in cellular biology.

I am using TMP21 (A-7): sc-137003 monoclonal antibody to stain paraffin embedded tissue. Do you recommend antigen retrieval when using this antibody?

Asked by: Randy McDonald
We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
