Documentation

Biosafety Icon BSL 2

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

Cells contain SV40 sequences

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Handling information

Unpacking and storage instructions
  1. Check all containers for leakage or breakage.
  2. Remove the frozen cells from the dry ice packaging and immediately place the cells at a temperature below ­-130°C, preferably in liquid nitrogen vapor, until ready for use.
Complete medium
The base medium for this cell line is DMEM/F-12 (ATCC 30-2006). To make the complete medium add the following components: 

  • hTERT Immortalized RPTEC Growth Kit (ATCC ACS-4007) with Supplement A (5 ml) and Supplement B (8ml)
  • 0.3 µg/mL puromycin
Temperature
37°C
Atmosphere
95% Air, 5% CO2
Handling procedure

To ensure the highest level of viability, thaw the vial and initiate the culture as soon as possible upon receipt. If upon arrival, continued storage of the frozen culture is necessary, it should be stored in liquid nitrogen vapor phase and not at -70°C.  Storage at -70°C will result in loss of viability.  

  1. Initial seeding density is 1x 104 and 2x104 viable cells/cm2. Thaw the vial by gentle agitation in a 37°C water bath. To reduce the possibility of contamination, keep the O-ring and cap out of the water.  Thawing should be rapid (approximately 2 minutes).
  2. Remove the vial from the water bath as soon as the contents are thawed, and decontaminate by dipping in or spraying with 70% ethanol. All of the operations from this point on should be carried out under strict aseptic conditions.
  3. Transfer the vial contents to a centrifuge tube containing  9.0 mL complete culture medium. and spin at approximately 125 x g for 5 to 7 minutes.
  4. Resuspend cell pellet with the recommended complete medium. It is important to avoid excessive alkalinity of the medium during recovery of the cells.  It is suggested that, prior to the addition of the vial contents, the culture vessel containing the complete growth medium be placed into the incubator for at least 15 minutes to allow the medium to reach its normal pH (7.0 to 7.6). pH (7.0 to 7.6).
  5. Incubate the culture at 37°C in a suitable incubator.  A 5% CO2 in air atmosphere is recommended if using the medium described on this product sheet.

         

Subculturing procedure
Volumes used in this protocol are for 75 cm2 flask; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes. Corning® T-75 flasks (catalog #430641) are recommended for subculturing this product.
  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with Phosphate Buffered Saline (PBS; ATCC 30-2200) solution to remove all traces of serum that contains trypsin inhibitor.
  3. Add 2.0 to 3.0 mL of Trypsin-EDTA for Primary Cells (ATCC PCS-999-003) to flask and observe cells under an inverted microscope until cell layer is dispersed (usually within 5 to 15 minutes).
    Note: To avoid clumping do not agitate the cells by hitting or shaking the flask while waiting for the cells to detach. Cells that are difficult to detach may be placed at 37°C to facilitate dispersal.
  4. 0.1% Soybean Trypsin Inhibitor (ATCC 30-2104) is then used to neutralize the trypsin. After neutralization, aspirate cells by gently pipetting.
  5. Remove Trypsin Inhibitor via centrifugation.
  6. Resuspend the cells with complete growth medium.
  7. Add appropriate aliquots of the cell suspension to new culture vessels.
    Cultures can be established between 1.0 x 104 and 2.0 x 104 viable cells/cm2.
  8. Incubate cultures at 37°C.
Interval: Maintain cultures at a cell concentration between 1.1X 104 and 1.5 X 105 cell/cm2.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:8 is recommended
Medium Renewal: 2 to 3 times per week

Functional tests
Functionality was validated during product development using both a 5-CF uptake assay and a 6-CF uptake assay. For the uptake assays, the cells were seeded on 96 well plate, 24 hours later, increasing concentrations of 5-CF or 6-CF were added in the HBSS buffer and incubated at 37°C for 20 minutes. The uptake was stopped by washing the wells with ice-cold HBSS, after 4 washes with HBSS, 100 µL of lysate buffer was added to each well, fluorescence intensity was measured using the Promega GloMax®-Multi Detection System Uptake ratio for both substrates was > than 5.
