MRP1 is a 190kD transmembrane phosphoglycoprotein overexpressed in various human multidrug resistant tumor cell lines and tumors .
Suitable for use in Immunocytochemistry, Flow Cytometry, Immunoprecipitation and Transport inhibition. Not recommended for use in Western Blot. Other applications have not been tested.
Immunocytochemistry: use on paraformaldehyde (0.5% in PBS) fixed cytospin preparations
Flow Cytometry: 0.2-1ug/ml after fixing cells in 0.5% paraformaldehyde, followed by suitable fluorescent tagged anti-mouse reagent (6)
Transport Inhibition: Inhibits the ATP-dependent transport activity of MRP1 in inside-out membrane vessicles.
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
|Non-denatured membranes prepared from the human small cell lung cancer cell line H69AR, which highly overexpresses MRP1.|
|Supplied as a liquid in PBS, 0.7% BSA, 0.1% sodium azide.|
|Recognizes a conformation-dependent internal epitope (aa617-932) of human MRP1 overexpressed in various human non-P-glycoprotein MDR tumor cell lines. Does not cross-react with human P-glycoprotein, MDR3 P-glycoprotein, or mouse MRP gene products.|
|Intended for research use only. Not for use in human, therapeutic, or diagnostic applications.|
