This FITC‑conjugated anti‑6xHis antibody offers bright, direct fluorescent detection of His‑tagged proteins without the need for secondary antibodies. Produced in chicken and supplied at 1 mg, this reagent provides strong specificity for the 6xHis epitope and stable FITC fluorescence, making it ideal for microscopy, flow cytometry, and rapid screening assays. Its low background and affinity‑purified quality support clear visualization and reliable quantification of His‑tagged constructs in protein localization studies, expression verification, and purification monitoring. A robust tool for fluorescence‑based His‑tag detection.
