Application Details

Application Notes: Peptide ELISA: antibody detection limit dilution 1:16,000. Western Blot: Approx 34kDa band observed in Human myeloid erythroblast cell line K562 and Human monocytic cell line U937 lysates (calculated MW of 34.0kDa according to NP_003992.3,). In transfected HEK293 transiently expressing CD32 a band of approx. 40kDa (glycoprotein) is observed. This band is not observed in the non-transfected HEK293. Recommended concentration: 0.3-1µg/ml.

Purification: Purified from goat serum by ammonium sulphate precipitation followed by antigen affinity chromatography using the immunizing peptide.

Buffer: 0.5 mg/ml in Tris saline, 0.02% sodium azide, pH7.3 with 0.5% bovine serum albumin.

Storage: Aliquot and store at -20°C. Minimize freezing and thawing.

Restrictions: For Research Use only
