ANTIBODIES
(anti-Human and others as indicated)
RDI Division of Fitzgerald Industries Intl offers a wide line of antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.
see monoclonal and polyclonals below: P-Glycoprotein, MDR and MRP Antibodies
Mab to Human P-Glycoprotein (P-gp)
cat#RDI-PRO57043, new cat#: 10R-G120a $656.25/vial
Clone Determination JSB-1
Category Mouse monoclonal
Form Culture Supernatant (with 1% BSA and 0.1% NaN3)
Immunoglobulin Class IgG1
Immunogen: Human P-gp
Clinical Application/Specificity: Mab JSB-1 reacts with a conserved cytoplasmic epitope of the plasma membrane associated P-gp, a 170 kD multidrug resitance-related protein. It detects P-gp overexpression in human tumor cells of all different histogenetic origins. Upon exposure to natural product drugs, tumor cells can aquire resistance to structurally and functionally unrelated drugs. The classical form of multidrug resistance (MDR) is caused by the p-glycoprotein (P-gp), a protein inserted in the plasma membrane and acting as an ATP-driven effiux pump. To the same superfamily of transport proteins belongs MDR-associated protein (MRP), a 180-195 kD glycoprotein. Also overexpression of the 110 kD Lung Resistance-related Protein (LRP) has been observed in several human non-P-gp MDR tumor cell lines.

Mouse Monoclonal Antibody To: Human MRD1 gene product
Product Code: RDI-CBL 428 $375.00/vial
Clone: C1
Isotype: IgG1
Immunizing Antigen: Variants of the T-lymphoblastoid leukaemic cell line
CCRF-CEM
Fusion Partner: SP2/0 myeloma cell line.
Source: Tissue culture supernatant
Purification Methods: Protein A affinity chromatography
Specificity: The multi-drug transport protein known as P-glycoprotein, 0170 or MDR1 gene production is directly related to the ability of selected drug resistant mammalian cell lines to proliferate in vitro in the presence of cylotoxic drugs. This plasma membrane bound protein has both cyloplasmic and extracellular domains. This antibody is known to specifically recognize the extracellular component and has definite application to the flow cytometric analysis of this molecule.

phosphate buffered saline containing 10mM sodium azide and 1mg/ml bovine serum
albumin. We recommend that each laboratory determine an optimum working
titre for use in it particular application.
Storage: For use within 1 month of purchase store at +4'C, for long term
storage aliquote antibody into small volumes and store at -20'C.

Immunoglobulin Class IgG1
Immunogen: Fusion protein containing 170 aa C-terminus with part of the carboxy-proximal nucleotide-binding domain of MRP protein.
Clinical Application/Specificity: Mab MRPm6 reacts with an internal epitope of MRP. It does not crossreact with the human MDR3 gene products. Upon exposure to natural product drugs,tumor cells can aquire resistance to structurally and functionally unrelated drugs. The classical form of multidrug resistance (MDR) is caused by the p-glycoprotein (P-gp), a protein inserted in the plasma membrane and acting as an ATP-driven effiux pump.

DATA SHEET:Mouse anti-human P-glycoprotein monoclonal
Catalog#: RDI-PGLYCO-MRK16
Price: $812.00/vial 150 micrograms
also available azide free cat#RDI-PGLYCO-MRK16X $875.00/150ug (NO BSA/No azide)
Supplied: purified via Protein A affinity chromatography, in PBS w/ 0.1% NaN3, 1%BSA
Clone: MRK16
Ig Isotype: Mouse IgG2a
Specificity: Reacts specifically with a surface epitope of human glycoprotein. Clone MRK16 reacts with P-Glycoprotein of human cortical adenomas and does not react with eochromocytoma, non functioning cortical adenoma, or myolipoma of the adrenal. MRK16 does not react with mouse P-glycoprotein. (other clones which react with inner membrane epitopes may cross-react with heavy chains of muscle myosin and/or type A blood).
Activity: Clone MRK16 binds to human P-Glycoprotein, a 170 kDa multi-drug resistance product that acts as an ATP-dependent efflux pump to remove drugs and other potentially harmful products from the cell interior. Research as linked multi-drug resistance in cancer cells to the over expression of P-glycoprotein. Since clone MRK16 reacts with P-glycoprotein exposed on the cell's surface, living cells can be labeled. After binding, MRK16 inhibits the function of P-glycoprotein. Glycoprotein-MRK16-protein A sepharose complex from the human adrenals possesses ATPase activity.
Uses: MRK16 shows good reactivity in FACS and immunoprecipitation. Frozen
tissue staining can be done providing that mild fixation treatment is used
(such as 4% paraformaldehyde. Acetone, paraffin, methanol and ethanol should
not be used). Not suitable for western blotting because the antibody loses its
structure in the presence of protein denaturing agents such as SDS..
For fACS use(purified antibody): 500K live cells
(fixation not necessary), add 50ul of ab (10 to 100ug/ml), incubate 30 minutes
on ice. Wash 3X with 10% FCS/PBS, add 20ul FITC-anti-mouse IgG, 15 minutes on
ice, Wash 3X with 10% FCS/PBS, 500ul PBS analyze.
-for biotin conjugate: use 300K cells, use FITC:Avidin
or Streptavidin-RED670 (see protocol with shipment).
For immunoprecipitation: 25-50ug/ml
For histostaining: 0.1-10ug/ml (approx)
Storage: Store at 4 Deg C. Aliquot and store at -20DEG C for long term storage. Avoid frequent freeze thaw cycles.
Precautions: For In vitro research Use Only. Not for use in or on humans or animals or for diagnostics. Sodium azide may form explosive compounds in presence of heavy metals or under acidic conditions. Flush drains with copious amounts of water to prevent buildup of explosive compounds.
