Anti-CD223 Antibody

Manufactured by Antibodies.com, this rabbit polyclonal reagent targets CD223 (also known as LAG-3, LAG3, FDC, or Lymphocyte activation gene 3 protein) and is validated for ELISA and Western blot workflows in human samples. The antibody was raised against a synthesized peptide derived from the internal region of human CD223 and detects endogenous levels of the target protein. It is supplied as an unconjugated, affinity-purified Ig fraction prepared from rabbit antiserum by epitope-specific affinity chromatography. The stock concentration is 1 mg/mL, formulated as a liquid in PBS containing 50% glycerol, 0.5% BSA, and 0.02% sodium azide. The 50 µl size is shipped at 4°C and should be aliquoted and stored at –20°C upon arrival, with repeated freeze/thaw cycles avoided to preserve performance. For Western blot, a representative image on the Antibodies.com product page shows detection in NIH-3T3 lysates, and the datasheet recommends starting dilutions suitable for standard ELISA and WB assays. This primary antibody is intended for research use only and is not cleared for diagnostic or therapeutic applications.
