| Disease |
killing cancer cells. |
| Applications |
The hybrid hybridoma cell lines 1B7 and 1A7 produce bispecific antibodies that recognize both the human Fc gamma receptor III (hFc gamma IIIR) and the multi-drug resistance antigen, P-glycoprotein. The 1B7 and the 1A7 antibodies are capable of binding to both the Fc receptors of cytotoxic cells, and tumor cells exhibiting multi-drug resistance phenotype, wherein the tumor cells over-express P-glycoproteins as compared to normal cells. These bispecific antibodies are useful in killing cancer cells. |
| Disclosure |

infringe the claims. Depending on the wishes of the Depositor, ATCC may be
required to inform the Patent Depositor of the party to which the material was
furnished. This material may not have been produced or characterized by ATCC. |

| Comments |
The hybrid hybridoma cell lines 1B7 (ATCC HB-10500) and 1A7 (ATCC HB-10501) were formed by the fusion of the 15D3 (ATCC HB-11342) and 3G8 hybridoma cell lines. The murine hybridoma 15D3 recognizes the human multi-drug resistance antigen, P-glycoprotein. The murine hybridoma 3G8 recognizes the human Fc gamma receptor III. The hybrid hybridoma cell lines 1B7 and 1A7 produce bispecific antibodies that recognize both the human Fc gamma receptor III (hFc gamma IIIR) and the multi-drug resistance antigen, P-glycoprotein. The 1B7 and the 1A7 antibodies are capable of binding to both the Fc receptors of cytotoxic cells, and tumor cells exhibiting multi-drug resistance phenotype, wherein the tumor cells over-express P-glycoproteins as compared to normal cells. These bispecific antibodies are useful in killing cancer cells. |
| Complete Growth Medium |
Iscove's modified Dulbecco's medium with 4 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate supplemented with 1% OPI (0.15 mg/ml oxaloacetate, 0.05 mg/ml pyruvate, 0.0082 mg/ml bovine insulin), 90%; heat-inactivated fetal bovine serum, 10%
|
| Subculturing |
Medium Renewal: Add fresh medium every 2 to 3 days (depending on cell density) Cultures can be maintained by the addition of fresh medium or replacement of medium. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 1 to 2 X 10 exp5 viable cells/ml. Maintain cell density between 1 X 10 exp5 and 1 X 10 exp6 viable cells/ml. |
