Comments
|
The cells are surface Ig negative (sIG-).
The cells are non-specific esterase, acid phosphatase and oil red O positive.
The cells are periodic acid Schiff negative.
These cells phagocytose Candida albicans and latex particles.
The cells are reported to be very weakly E - rosette positive.
ATCC confirmed this cell line is negative for the presence of Epstein-Barr viral DNA sequences via PCR.
