Cell markers are a unique set of proteins located on the cell surface that enable the identification, classification, and visualization of cells with antibodies; these antibodies can be directed against a singular target or multiple targets depending on the cell type and the unique set of cell markers present. Organelle markers, also known as subcellular markers, are proteins that are specific to an organelle; these enable the identification and visualization of these structures with antibodies.
Epitope tags are short peptide sequences, generally composed of 10 – 15 amino acids, designed to create a molecular handle for a protein. An epitope tag can be placed anywhere within a protein, but typically is placed on either the C-terminus or N-terminus in order to minimise tertiary structure disruptions that may alter protein function. By introducing a unique sequence of amino acids into a recombinant protein, antibodies against the corresponding epitope tag can be used to track protein expression and visualise the protein in tissues, cells, and organelles.
We offer a comprehensive portfolio of antibodies, proteins, and assays, for detecting & quantifying tags and cell markers, that exhibit high specificity, activity, performance, and reproducibility in a range of techniques, including: Western Blot (WB), Immunohistochemistry (IHC), Immunofluorescence (IF), Immunocytochemistry (ICC), and ELISA.
