CD274 Antibody

SKU: orb1247125

Description

CD274 Antibody

Images & Validation

• Tested Applications: ELISA, FC, IF, IHC, WB
• Reactivity: Human
• Application Notes:
  Peptide ELISA: antibody detection limit dilution 1:128000.Western Blot:Approx 40kDa band observed in Human Heart lysates. The observed molecular weight corresponds to glycosylation (calculated MW of 33.3kDa according to NP_054862.1). An additional band was also consistently observed at 55kDa, and was successfully blocked by incubation with the immunizing peptide. Preliminary testing also showed the 37+55kDa bands in lysates of cell lines, A549, Daudi, HeLa, HepG2 and Jurkat Recommended concentration: 0.03-0.1ug/ml. Primary incubation 1 hour at room temperature.Immunohistochemistry:In paraffin embedded Human Placenta shows membranous staining of cytotrophoblasts. Recommended concentration: 2-4ug/ml.Immunofluorescence: Strong expression of the protein seen in the cytoplasm of A431 and U2OS cells. Recommended concentration: 10ug/ml. Flow Cytometry: Flow cytometric analysis of Jurkat cells. Recommended concentration: 10ug/ml.
