Description

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.
