Applications
Neuroretina (NR) is an evagination of the central nervous system (CNS) which is composed of photoreceptors; glial (Muller) cells; horizontal, bipolar, amacrine; and ganglion neuronal cells.
They have high glutamic acid decarboxylase (GAD) activity and they bind monoclonal antibodies raised against chick embryo neuroretina.
Storage Conditions liquid nitrogen vapor phase
Comments
Neuroretinas were dissected from normal quail embryos, dissociated and immortalized by infection with Rous sarcoma virus (RSV) mutant ts NY-68 to establish the QNR ts NY-68 mixed cell line.
QNR ts NY-68 was subsequently cloned to establish the QNR/D cell line. The cells are routinely maintained at 38.5 to 39C. The permissive temperature for transformation is 36C.
Neuroretina (NR) is an evagination of the central nervous system (CNS) which is composed of photoreceptors; glial (Muller) cells; horizontal, bipolar, amacrine; and ganglion neuronal cells.
The cell line displays properties of amacrine and/or ganglion cells.
QNR/D cells can generate tetrodotoxin(TTX)-inhibitable action potentials on electrical stimulation. They have high glutamic acid decarboxylase (GAD) activity and they bind monoclonal antibodies raised against chick embryo neuroretina.
QNR/D cells (ATCC CRL-2532) and QNR/K2 cell (ATCC CRL-2533) were transplanted into chicken embryo eyes. Implanted QNR/D cells migrate only to the retinal ganglion and amacrine cell layers and project neurites in the plane of retina.
In contrast, QNR/K2 cells migrate through the ganglion and amacrine layers, locate in the inner nuclear layer, and project processes across the retina.
Complete Growth Medium The base medium for this cell line is ATCC-formulated Dulbecco's Modified Eagle's Medium, Catalog No. 30-2002. To make the complete growth medium, add the following components to the base medium: fetal bovine serum to a final concentration of 10%.
Subculturing
Protocol:
  1. Remove and discard culture medium.
  2. Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum which contains trypsin inhibitor.
  3. Add 2.0 to 3.0 ml of Trypsin-EDTA solution 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. Add 6.0 to 8.0 ml of complete growth medium and aspirate cells by gently pipetting.
  5. Add appropriate aliquots of the cell suspension to new culture vessels.
  6. Incubate cultures at 38.5°C.to 39°C
