A selection guide for Claudin-4 reagents: full-length vs. extracellular domain, His-tag and detergent formulation, and how to pick a membrane protein prep for binding and structural work.

A practical guide to recombinant P53 protein as a research reagent: tag format, purification, activity validation, and how to design DNA-binding, reporter and mutant-comparison experiments around P53.

FITC-labeled TSLP is a flow cytometry tool for CAR-positive cell verification. This article reviews FITC labeling principles, HEK293-derived antigen QC, flow platform parameters and a three-class control troubleshooting path.

FITC-Labeled CD7 His Tag Protein is a recombinant detection tool consisting of the extracellular domain of the T-cell surface marker CD7 fused with a histidine tag and covalently labeled with fluorescein isothiocyanate (FITC). As a specific probe for a key marker of T lymphocyte and NK cell activation, it holds irreplaceable value in the diagnosis and classification of T-cell acute lymphoblastic leukemia, certain autoimmune diseases, immunodeficiency disorders (such as HIV infection), and the development of cutting-edge cell therapies.
