Murine L cell transfectants expressing human CD40

Human CD40 is a member of the tumor necrosis factor (TNF) receptor family and is present on all B cells except plasma cells. CD40 is also found on some epithelial cells, carcinomas and lymphoid dendritic cells. CD40 plays an important role in B cell activation and the interaction with its ligand (CD40 Ligand) is essential for isotype switching.

Applications:
Suitable for use in ELISA and Flow Cytometry. Other applications not tested.

Recommended Dilution:
Flow Cytometry: 5x10e5 cultured Raji human tumor cells were incubated 45 min on ice with 80ul of anti-CD40 antibody at 5ug/ml. Cells were washed twice and incubated with Goat anti-Mouse IgG/FITC, after which they were washed three times, fixed and analyzed by FACS. Cells stained positive with a mean shift of 1.46 log10 fluorescent units when compared to a Mouse IgG1 negative control at a similar concentration.
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
