RFLG‑45F is a FITC‑conjugated rabbit antibody targeting the DYKDDDDK (FLAG) epitope, optimized for fluorescence‑based detection of FLAG‑tagged proteins. The fluorescein label enables direct visualization in microscopy, flow cytometry, and fluorescent immunoassays. Affinity purification ensures high specificity and reduced background, producing bright, clear signals across imaging and analytical platforms. Manufactured by Immunology Consultants and supplied in a 1 mg format, RFLG‑45F is an excellent choice for researchers requiring a fluorescently labeled anti‑FLAG reagent
