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.

Applications
M2 cells are severely deficient in filamin-1 mRNA and protein.
The filament-1 gene on the X chromosome is present in these cells.
A7 cells are useful as a control for studying these systems.
Storage Conditions liquid nitrogen vapor phase
Genes Expressed
filamin-1 (actin-binding protein ABP or ABP-280)
Cellular Products
filamin-1 (actin-binding protein ABP or ABP-280)
Comments
M2 cells are severely deficient in filamin-1 mRNA and protein. Filamin-1, also known as actin-binding protein (ABP, APB-280), cross-links actin filaments in vitro and connects these filaments to plasma membrane glycoproteins.
The filament-1 gene on the X chromosome is present in these cells.
ABP (filamin-1) was transfected into M2 cells in a mammalian expression vector (LK444) containing full length human ABP recombinant DNA (LK-APB).
A7 cells express levels of filamin-1 comparable to wild-type filamin-1 containing melanoma cells.
Filamin-1 is essential for cell migration and has been shown to bind partners in cell signal transduction, cell membrane sorting and cytoskeleton-membrane association.
A7 cells are useful as a control for studying these systems.
Complete Growth Medium The base medium for this cell line is ATCC-formulated Eagle's Minimum Essential Medium, Catalog No. 30-2003. To make the complete growth medium, add the following components to the base medium:
  • 10 mM HEPES
  • 0.5 mg/ml G418
  • fetal bovine serum to a final concentration of 10%

Subculturing
Protocol: Remove medium, and rinse with 0.25% trypsin - 0.53 mM 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.
Subcultivation Ratio: A subcultivation ratio of 1:4 to 1:8 is recommended
Medium Renewal: Every 2 to 3 days
Cryopreservation
Freeze medium: culture medium 95%; DMSO, 5%
Storage temperature: liquid nitrogen vapor phase
Culture Conditions
Temperature: 37.0°C
Name of Depositor TP Stossel
