Analysis of p-glycoprotein expression in skeletal and cardiac muscle revealed that C219 cross reacts with a 200kDa protein that migrates in the same position as myosin. C219 has also been reported to detect the 185kDa c-erbB2 protein (Liu, et al 1997). Care should be taken in the interpretation of true positive P-glycoprotein expression when using myosin-containing tissues or tissues known to have p185 c-erbB2 expression.
Note: Not all species have been tested for usefulness with this product. Only those species listed have been tested. We cannot make any guarantees about additional reactivities which may or may not occur.
SDS-solubilized plasma membranes of a multidrug resistant Chinese hamster ovary (CHO) cell line and a human cell line.
Localization:
Cell Membrane; Integral membrane protein
Epitope:
This antibody recognizes an internal, highly conserved amino acid sequence: VQEALD and VQAALD, corresponding to the C-terminal and N-terminal regions, respectively, found in both MDR1 and MDR3 isoforms of P Glycoprotein. The specific binding of the clone
Species Reactivity:
Cross-reacts with Human and Rat. Expected to cross-react with wide range of Mammals due to highly conserved epitope sequence. Not yet tested in other species.
Applications:
Uses:
IHC-P: Use for Biotin-based detection systems. Sections should be pre-treated with an antigen unmasking solution. Predicted molecular weight: 141 kDa. *Human liver (positive staining detected along luminal surfaces of bile canaliculi) or human colon (positive staining localized to luminal surface of secretaory epithelium) can be used as positive controls for IHC. **For optimal staining, the primary antibody should be incubated 60 minutes at room temperature. NOTE: Optimal dilutions/concentrations should be determined by the end user.
Dilutions:
Immunocytochemistry, Immunohistochemistry-Frozen 1/25, Immunohistochemistry-Paraffin 1/25, Immunoprecipitation, Western Blot
