Figure 1: Effect of anti-HER2 monoclonal
antibody herceptin on SK-BR-3 cell proliferation. Cell number was determined on the third, seventh and tenth day using the hemocytometer. (A) 3000
cells/ml per well were seeded on day 0.
(B) 10,000 cells/ml per well were seeded. Each count was done in duplicate with the error bars
representing +/- SD.
