[Text version]
Cell line name 1.1B4
Accession CVCL_1778
Resource Identification Initiative To cite this cell line use: 1.1B4 (RRID:CVCL_1778)
Comments Group: Patented cell line.
Problematic cell line: Misidentified/contaminated. Originally thought to be an hybrid cell line obtained by electrofusion of a primary culture of human pancreatic islets with the PANC-1 but found to contain rat DNA (ECACC=10012801; PubMed=34341375).
Registration: International Cell Line Authentication Committee, Register of Misidentified Cell Lines; ICLAC-00599.
Registration: International Depositary Authority, European Collection of Cell Cultures (ECACC); 00112811.
Characteristics: Insulin secreting.
Doubling time: 23 +- 1.7 hours (PubMed=21515691); ~20 hours (ECACC=10012801).
