Cell Line Origin
A human pancreatic Beta cell: PANC-1 hybrid cell line. Insulin-secreting cell line.
Cell Line Description
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. 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.

Culture Medium
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 approximately 20 hours. 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.

Obesity is characterized by increased systemic and pulmonary blood volumes (pulmonary vascular congestion). Concomitant abnormal alveolar membrane diffusion suggests subclinical interstitial edema. In this setting, functional abnormalities should encompass the entire distal lung including the airways. We hypothesize that in

Beta thalassemia major (βT) is a hereditary anemia characterized by transfusion-dependency, lifelong requirement of chelation, and organ dysfunction. MicroRNA (miRNA) can be packed into extracellular vesicles (EVs) that carry them to target cells. We explored EV-miRNA in βT and their

Characterizing relationships between cell structures and functions requires mesoscale mapping of intact cells showing subcellular rearrangements following stimulation; however, current approaches are limited in this regard. Here, we report a unique application of soft x-ray tomography to generate three-dimensional reconstructions
