Primary Human Primary Keratinocytes (ACBRI 2K0) were isolated from dispase dissociated dermal tissue. Unlike cells from other providers, Cell Systems primary cells are isolated without positive control antibody labels. Each vial contains ~1 x 10^6 cells with 85-92% viability under ideal conditions. They are available at Passage 3 (<12 cumulative population doublings) and will initiate a Passage 4 cell culture in a 75 cm2 flask. Each vial of cells is shipped with Bac-Off (antibiotic) and CultureBoost (animal derived growth factors) at no additional cost. These cells require specialized low-calcium Keratinocyte media. You can enhance consistency in your research program with reserved lots. Need vials in bulk? Contact Fisher Scientific Sales rep for tailored quotes. Tight Deadline?
