Technical Data
A431 Cells, Non-Stimulated in RIPA Buffer, Sample Buffer
Biologicals Storage: -20CShipping: Blue Ice
Cellular protein preparation from human A431 cells

Suitable for use in Western Blot. Other applications not tested.

Recommended Dilutions:
Add 2.5ul of 2-mercaptoethanol/100ul of lysate and boil for 5 minutes to reduce the preparation. Load 20ug of reduced lysate per lane for Western Blot analysis. This preparation may be used as a positive control for antibodies.

Storage and Stability:
May be stored at 4C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20C. Aliquots are stable for 6 months after receipt at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
Source: Human A431 cells
