CAS:5-Fluorescein isothiocyanate isomer I (5FITC) is a fluorescent probe that has been used to study enzyme activities in human serum. 5FITC binds to the active site of many enzymes, including dopamine β-hydroxylase, and can be detected by measuring the fluorescence intensity. The optimum concentration for this enzyme form is 10 nM for dopamine β-hydroxylase and 20 nM for brain functions. Mouse monoclonal antibodies against 5FITC have also been developed to detect the presence of toll-like receptor 4 (TLR4) on macrophages in vivo. 5FITC has also been used as a fluorescence probe for human immunoglobulin G (IgG) and erythrocytes in blood samples. Colloidal gold conjugates with 5FITC have been developed to measure the disulfide bonds in proteins such as human serum albumin.Formula:C21H11NO5SPurity:Min. 95%Molecular weight:389.38 g/molFluorescein 5-Isothiocyanate, Isomer 1, 95%

CAS:Fluorescent labeling reagent for proteins. FITC-conjugated antibodies are commonly used in immunohistochemistry for immunofluorescent staining. Fluorescein isothiocyanate (FITC) is a yellow-green colored low molecular weight dye which couples to proteins via reaction with primary amine groups at high pH. FITC is excitable at 488nm, close to its absorption maximum at 494nm, and produces maximum fluorescence emission around 520nm. It is commonly conjugated with antibodies for use in indirect immunofluorescence.Formula:C21H11NO5SPurity:Min. 90.0 Area-%Molecular weight:389.39 g/mol
