C219 MDR
Multidrug Resistance
Clone: C219
C219 recognizes an internal, highly
conserved amino acid sequence (VQEALD & VQAALD) found in both Mdr1 and
Mdr3 isoforms of P-glycoprotein. The specific binding of the clone C219
was stronger in epitope sequence VQAALD (N-Terminal fragment) than the
epitope sequence VQEALD (C-terminal fragmant) (Geoges E., et al.,
(1990). C219 is not species-specific. Immunohistochemical analysis of
rat and human skeletal and cardiac muscle, as well as immunoblots of
cardiac muscle tissue, have shown that C219 cross-reacts with a Mr
200,000 protein which migrates in the same position as myosin. Also, in
a recent publication, Liu BL., et al., has reported that the C219 mAB
cross-reacts with the c-erbB2 protein (p185 c-erbB2). 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.
