Comments

ATCC® VR-1492PQ™ is a high-titer, purified, live virus suspended in 10 mM Tris-HCL (pH 7.5) with 135 mM NaCl, 0.5% BSA, and 5% Trehalose. This product was prepared from ATCC® VR-1492™ via purification by tangential filtration.

This EBV preparation is capable of transforming B-lymphocytes from a preparation of normal human lymphocytes when co-cultivated with a feed layer culture (such as ATCC® 55-X™).

Quality control testing is done by transformation assay instead of TCID50.

Effect on Host
EBV transforms/immortalizes human and other primate B-lymphocytes. Indicators of transformed cells include cone-shaped cells, cells with spike-like projections, and small clusters of healthy cells.
Recommended Host
B95-8 cells
Growth Conditions

Temperature: 37°C

Recommendations for Infection: This EBV preparation is capable of transforming B-lymphocytes from a preparation of normal human lymphocytes when co-cultivated with a feed layer culture (such as ATCC® 55-X™).

Incubation: 10-25 days at 37°C in a humidified 5% CO2 atmosphere, until indicators of successful transformation appear.

Effect on Host
EBV transforms/immortalizes human and other primate B-lymphocytes. Indicators of transformed cells include cone-shaped cells, cells with spike-like projections, and small clusters of healthy cells.
Name of Depositor G Miller
Source Human lymphoblastoid cell line (883L) derived from a patient with transfusion-induced infectious mononucleosis.

FAQs
  1. Quantitating VR-1492PQ for infectivity

    VR-1492PQ is measured for infectivity by observance of transformation in the test flask and the positive control. See Technical Bulletin #10 for the procedure used.
