Background Information	CD4 (T4, Leu3a) is a 55 kDa single-chain transmebrane glycoprotein expressed on a subset of T lymphocytes (''helper'' T-cells) and also on monocytes, tissue macrophages and granulocytes. In extracellular region there are 4 immunoglobulin-like domains (1 Ig-like V-type and 3 Ig-like C2-type). Transmembrane region forms 25 aa, cytoplasmic tail consists of 38 aa. Domains 1, 2 and 4 are stabilized by disulfide bonds. The intracellular domain of CD4 is associated with p56Lck, a Src-like protein tyrosine kinase.
Usage	The reagent is designed for Flow Cytometry analysis. Suggested working usage is 3·µg/ml. Indicated dilution is recommended starting point for use of this product, but working concentrations should be validated by the investigator.
Storage Buffer	The reagent is provided in phosphate buffered saline (PBS) solution, pH ≈7.4, containing 0.09% (w/v) sodium azide.
Storage	Avoid prolonged exposure to light. Store in the dark at 2-8°C. Do not freeze.
Stability	Do not use after expiration date stamped on vial label.
