商品貨號 B163964
Organism Mus musculus, mouse
Product Format frozen
Morphology spindle shape
Culture Properties adherent
Biosafety Level 2

Biosafety classification is based on U.S. Public Health Service Guidelines, it is the responsibility of the customer to ensure that their facilities comply with biosafety regulations for their own country.
Disease sarcoma
Strain LAF1
Applications
This line was derived from an AtT-20ins cell line in which the Rous sarcoma virus long terminal repeat was used for directing insulin cDNA expression.
The cell line produces glucose-stimulated insulin release in both static incubation and perifusion studies.
The cell line is resistant to 0.25 mg/ml G-418 and 0.12 mg/ml hygromycin B.
The presence of the GLUT-2 transgene can be confirmed by Northern blot analysis.
Disclosure This material is cited in a US or other Patent and may not be used to infringe the claims. Depending on the wishes of the Depositor, ATCC may be required to inform the Patent Depositor of the party to which the material was furnished. This material may not have been produced or characterized by ATCC.
Derivation
This line was derived from an AtT-20ins cell line in which the Rous sarcoma virus long terminal repeat was used for directing insulin cDNA expression.

Comments
This line was derived from an AtT-20ins cell line in which the Rous sarcoma virus long terminal repeat was used for directing insulin cDNA expression.
AtT-20ins cells were transfected by eclectroporation with rat islet GLUT-2 cDNA cloned into the vector pCB-7 immediately downstream of its cytomegalovirus promotor. The pCB-7 vector contains a hygromycin resistance marker.
The cell line produces glucose-stimulated insulin release in both static incubation and perifusion studies.
The cell line is resistant to 0.25 mg/ml G-418 and 0.12 mg/ml hygromycin B.
The presence of the GLUT-2 transgene can be confirmed by Northern blot analysis.
Complete Growth Medium The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Subculturing
Subcultivation Ratio: A subcultivation ratio of 1:4 is recommended
Medium Renewal: Every 2 to 3 days
Remove medium, and rinse with 0.25% trypsin, 0.03% EDTA solution. Remove the solution and add an additional 1 to 2 ml of trypsin-EDTA solution. Allow the flask to sit at room temperature (or at 37C) until the cells detach.
Add fresh culture medium, aspirate and dispense into new culture flasks.
Cryopreservation
FBS, 50%; Complete growth medium ,40%; DMSO, 10%
Culture Conditions
Temperature: 37.0°C
Name of Depositor Univ. Texas System
Deposited As mouse
U.S. Patent Number
