Anti-Hu CD4, OKT4, FI, 100tests

STEMCELL Technologies supplies a mouse monoclonal antibody targeting human CD4, provided as a FITC-conjugated reagent intended for flow cytometry applications. The clone OKT4 recognizes CD4, a cell-surface molecule expressed by most thymocytes and a subpopulation of T cells. The preparation is presented as a clear liquid for laboratory research use and may be combined with other markers such as anti-human CD45 in multi-color flow cytometry panels applied to human peripheral blood mononuclear cells.

Per the manufacturer's safety data sheet, the antibody is not classified as a hazardous substance or mixture under the Globally Harmonized System (GHS), and the exact composition concentration is withheld as a trade secret. The documentation states that 0% of the mixture consists of ingredients of unknown acute toxicity, and that no special protective equipment is required under normal handling conditions. Standard practices apply: handle in accordance with good industrial hygiene and safety practice, rinse thoroughly with water on eye contact, wash skin with soap and water, and remove to fresh air if inhaled.

Storage conditions are specified in the Product Information Sheet accompanying the reagent. The product is suited to immunophenotyping workflows that include flow cytometry analysis of human PBMCs, and is referenced for use in workflows involving immunomagnetic negative isolation of untouched human CD4+ T cells directly from whole blood.
