GENERAL INFORMATION Human A431 Epidermoid Carcinoma Cells were
isolated from a female patient with epidermoid carcinoma. The Universal
Growth Medium (UGM, UBP-01B, containing 10%FBS) is recommended for the cell
culture.

CHARACTERIZATION OF
THE CELLS
|
|
1.

A431 cells are negative
for HIV-1, HBV, HCV, and mycoplasma
|
|
PRODUCT USAGE Cells are offered for Research Use Only.

HANDLING OF ARRIVING
CELLS When you receive the
dry ice package with cells in frozen vials, transfer the frozen vials of
cells into a -80C freezer for short period storage or a liquid nitrogen tank
for long- term storage.

PROTOCOLS FOR
THAWING THE CELLS AND SUBCULTURE
|
|
A)
|
Pre-coating of T25
flasks- Add 2ml each Universal Coating Solution (UBP-01) into a T25 flask to
cover the whole surface of the flask, 5 mins later, dispose the excessive
coating solution by aspiration and the flask is ready to be used.
|
|
B)
|
Thaw the frozen cell
vial in a 37C water bath first, and then transfer the cells into the
pre-coated T25 flask with 10ml of UBP-01B medium, cells usually become
confluent overnight and ready to be passaged.
|
|
C)
|
To passage the
cells, rinse the cells in a T25 flask with 5ml HBSS (RT) twice; then add 2ml Universal
Detachment Solution (RT) (UBP-23) into one T25 flask; gently dispose the
excessive Universal Detachment Solution within 20 seconds by aspiration.
|
|
D)
|
Leave the T25 flask
with the cells at RT or 37C for 1 min (most cells usually will detach from
the surface within 1-2 mins; or monitor the cells under a microscope until
most of cells become rounded up, and then gently tap the flask against the
bench surface, and the cells will move on the surface of the flask when
monitoring under microscope.
|
|
E)
|
Add 5ml Universal Neutralization
Buffer and spin down the cells with 800g centrifugation for 5 mins.
|
|
G)
|
Re-suspend the cell
pellet with 10 or 15ml UBP-1B medium and transfer 5 ml each into 2 or 3
pre-coated T25 flasks (for 1/2 to 1/3 subculture ratio).
|
|
H)
|
Change medium every
2 or 3days and the cells usually become confluent within 7 days (when split
at a 1/3 ratio).
|
|
I)
|
To prepare quiescent
cells, when cells are nearly confluent, replace UBP-01B with Endothelial
Basal Medium (UBM, MED02 ) containing 0.5%FBS for about 8-12hrs before your
experiments.
