Frequently Asked Questions

Frequently Asked Questions are available for this Product.

Application

Reagent for the FITC labeling of proteins; Microsequencing of proteins and peptides (HPLC)

Biological applications include use as a fluorescent labeling reagent for proteins, a fluorescent reagent for protein tracing, and a reagent in the fluorescent antibody technique for the rapid identification of pathogens. FITC is yellow-orange in color with an absorption maximum at 495 nm. Upon excitation it emits a yellow-green color with an emission maximum at 525 nm.

Fluorescein isothiocyanate isomer I is suitable reagent for protein labeling studies. It may be employed as the derivatization reagent for amphetamine, methamphetamine, 3,4-methylenedioxymethamphetamine and P-phenylethylamine in human urine during their capillary electrophoretic (CE) determination. It may be used for the preparation of fluorescent antibodies. It was employed for in vitro sensitization studies.
