Biotinyl tyramide is used in immunohistochemistry (IHC) and in situ hybridization (ISH) protocols. Tyramide Signal Amplification (TSA) is an immunohistochemistry technique designed to detect and quantify molecules such as proteins and nucleic acids. Biotinyl tyramide acts as an amplification reagent in these assays by catalyzing the deposition of a biotin polymer. Tyramide mimics tyrosine, forms a covalent bond with a tyrosine residues. This results in an increased signal intensity, allowing for enhanced detection and protein visualization. The biotinylated molecules can then be further detected using streptavidin-conjugated enzymes or fluorescent probes.

In how much DMSO does this have to be dissolved and at what dilution would it be used for a signal amplification in immunofluorescence or immunohistochemistry?

Asked by: Mememe
Thank you for your question. This compound has a solubility of 3mg/ml in DMSO. Unfortunately we do not have any information on the dilution for signal amplification. Please contact Technical Service by phone, (800)-457-3801 option 2, email <scbt@scbt.com>, or by live chat directly on our website, www.scbt.com if you have any further questions.
