Cell Line Description

1.2B4 is a hybrid cell line formed by the electrofusion of a primary culture of human pancreatic islets with HuP-T3, a human pancreatic carcinoma cell line (Sigma catalog number 93121055). 1.2B4 has been shown to be tumourigenic when transplanted into a SCID mouse host. The cell line has applications in the study of pancreatic cell biology. 1.2B4 cells provide a method of producing pure insulin secreting cells. This is an alternative to the use of primary tissue in cell transplantation therapies for type 1 diabetes.

Culture Medium

RPMI-1640 + 2 mM Glutamine + 10% FCS / FBS

Subculture Routine

Split sub-confluent cultures (70-80%) 1:2 to 1:6 , i.e., seeding at 2-4 x 104 cells/cm2 using 0.25% trypsin or trypsin/EDTA; 5% CO2; 37 °C. Population doubling approx 20hrs. At confluence 105 cells/cm2 can be expected.

Other Notes

Cultures from HPA Culture Collections and supplied by Sigma are for research purposes only. Enquiries regarding the commercial use of a cell line are referred to the depositor of the cell line. Some cell lines have additional special release conditions such as the requirement for a material transfer agreement to be completed by the potential recipient prior to the supply of the cell line. Please view the Terms & Conditions of Supply for more information.
