CBP61117
I. General information 
Synonyms: 1.1B4
Background: The hybrid cell line1.1B4 was formed by the electrofusion of a primary culture of human pancreatic islets with PANC-1, a human pancreatic ductal carcinoma cell line (ECACC catalogue number 87092802).
According to the literature (Vasu et al 2013) (Green et al 2015) 1.1B4 secretes a low level of insulin as detected by radioimmunoassay (see protocol below). 1.1B4 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
The STR profile of 1.1B4 is indistinguishable from the parental PANC-1 Cell Line indicating that the DNA from the pancreatic beta cell fusion partner is below the limit of detection of the STR profiling assay. The Y chromosome could not be detected in this cell line by short tandem repeat (STR)-PCR analysis when tested at ECACC. It is a known phenomenon that due to the increased genetic instability of cancer cell lines the Y chromosome can be rearranged or lost resulting in lack of detection. The cell line is identical to the source provided by the depositor based on the STR-PCR analysis.
