Swiss Prot Num:
Application Western blot: Use an anti-Mouse-HRP.
Immunocytochemistry on Aceton Fixed Cell Preparation: at least 1/20. 
Flow Cytometry: 1/10. Cell permeabilization in 10% (v/v) Lysing solution followed by primairy antibody and anti-Mouse-FITC required. 
Immunohistochemistry on Acetone-Fixed Frozen Sections: 1/20 
Immunohistochemistry on Formalin-Fixed Paraffin Embedded Sections: 1/20.  
Optimal staining results are obtained with routine 2-step ABC or APAAP methods using acetone fixed cytocentrifuge preparations or cryostat sections. 
In case the B-5 fixative is used (See Protocols) also paraffin embedded tissue can be stained with the antibody.
Background P Glycoprotein, the product of the MDR1 gene, is expressed in distinct non-malignant cells, typically cells with secretory and excretory functions. It is assumed to function as an ATP-dependent drug efflux pump with broad substrate specificity. The highest expression of P Glycoprotein has been observed in kidney (proximal tubules), liver (bile canaliculi), adrenal gland and intestine, suggesting that the primary role of P Glycoprotein is in the normal secretion of physiological metabolites and ingested chemicals into bile, urine and the lumen of the intestinal tract. Elevated levels of P Glycoprotein have also been reported in multidrug-resistant cell lines and in colon, endometrial, ovarian, and breast tumors, as well as in sarcomas and leukemias / lymphomas.
Concentration approx. 0.25 mg/ml
Protocols B-5 Fixative:
Fix tissue in freshly prepared B-5 fixative: add 2 ml of 40% formalin to 20 ml of B-5 Stock Solution. Sections must be dezenkerized to remove mercuric pigment before immunostaining. Dezenkerize by placing slides with sections in Gram's Iodine solution for 5 min. at room temperature. Wash well in distilled water. Place slides in Sodium Thiosulphate solution for 5 min. at room temperature. Wash in running tap water for 3 min. Place in PBS for further immunochemical procedures.

B-5 Stock Solution
12 g Mercuric Chloride
2.5 g Sodium Acetate
dissolve in 200 ml distilled water.

Gram's Iodine
1 g I2
2 g KI
dissolve in 300 ml distilled water.

Sodium Thiosulphate solution
15 g Na2S2O3*5H2O
dissolve in 300 ml distilled water.

The antibody JSB-1 recognizes a strongly a conserved cytoplasmic epitope of the plasma membrane-associated 170-180 kD glycoprotein, the expression of which is strongly correlated with the degree of multi-drug-resistance (MDR) derived MDR cell lines and human MDR cell lines, including cell lines derived from lung, ovaries and B cell lymphomas.
