Product Name:
|
Sup-T1 Cells Infected with Human Herpesvirus 7 (HHV-7), JI
|
|
Manufacturer:
|
BEI Resources
|
|
Material Provided:
|
Each vial contains approximately 1.0 mL of frozen cells in RPMI 1640 medium supplemented with 20% fetal bovine serum and 5% dimethyl sulfoxide (DMSO). Sufficient cells are provided to initiate at least one new culture. The cell count, expressed as cells/vial, is shown on individual Certificates of Analysis for each lot.

|
Packing/Storage:
|
This product was packaged aseptically in cryovials. It should be stored at -100°C or colder, preferably in the vapor phase of a liquid nitrogen freezer. Storage at -70°C will result in loss of viability. To ensure the highest level of viability, the vial should be thawed and the culture initiated as soon as possible upon receipt. Any warming of the product during shipping and transfer must be avoided, as this will adversely affect the viability of the product after thawing. For the transfer between freezers and shipping, the cells may be placed on dry ice for brief periods, although the use of a portable liquid nitrogen carrier is preferred. Please read the following recommendations prior to culturing this material.

Safety Precautions:
|
When handling frozen vials, it is highly recommended that protective gloves, lab coat and full-face mask be worn. Even brief exposure to the ultra-cold temperature can cause tissue damage from frostbite. Also, some vials may slowly fill with liquid nitrogen if they have been immersed during cryogenic storage. When thawing, the liquid nitrogen may rapidly expand as it changes to gas, breaking the vial or cap with explosive force, sending debris flying with enough velocity to cause injury. Store and use in areas with adequate ventilation

Thawing and Growth:
|
Note: It is recommended that you have a culture of fresh, uninfected Sup-T1 cells (BEI Resources ARP-100) prepared when thawing HRP-12148. Feed infected cells with uninfected Sup-T1 cells at a ratio of 1:5 (infected to uninfected). Gently pipette the cells a few times to break up clumps and allow for a more robust cell expansion.
Prior to thawing the cells, prepare growth medium (GM) for use. HRP-12184 is grown in RPMI 1640 medium supplemented with 10% fetal bovine serum.
Rapidly thaw the vial of cells in a 37°C water bath with gentle agitation. To reduce the risk of contamination, keep the cap and O-ring of the vial out of the water and repeatedly check the cap for tightness during thawing. Remove from the water bath immediately when thawed. Dry the vial with a sterile wiper, decontaminate using a
wiper soaked with 70% isopropyl alcohol, and let the vial air dry. Aseptically open the vial, remove the vial contents and add 4.0 mL of GM in a centrifuge tube. Centrifuge the cell suspension at 150 × g for 8 to 10 minutes at 18°C to 25°C. Discard the supernatant and resuspend the cell pellet in 10 mL of pre-warmed GM. Transfer the cell suspension into a 75 cm2 flask. Incubate the new culture at 37°C and 5% CO2.
Sub-culture procedure:
Cultures can be maintained by the addition of fresh GM or the replacement of GM. Alternatively, cultures can be established by centrifugation with subsequent resuspension at 2.0 × 105 cells/mL. Maintain a cell density between 1.0 × 106 and 1.2 × 106 cells/mL. To replace the GM, centrifuge the cell suspension at 150 to 300 × g for 8 to 10 minutes at 18°C to 25°C, remove the supernatant and resuspend the cell pellet in fresh pre-warmed complete GM to the desired cell density. Add fresh medium every 2 to 3 days, depending on cell density.
