| Derivation |
The clone#1934 aIL8.42 NB 28605/14 cell line was derived by co-transfecting the CHO cell line DP-12 using Lipofection with the vector p6G4V11N35E.choSD.10 designed to coexpress variable light and heavy regions of the murine 6G4.2.5 monoclonal antibody (ATCC HB-11722). Clones were selected in methotrexate. |
| Comments |
The cells are reported to produce 250 mg/L recombinant human anti-IL-8. Both the clone#1933 (ATCC CRL-12444) and clone#1934 (ATCC CRL-12445) antibodies inhibit IL-8 binding to human neutrophils. They also show equivalent neutralizing capabilities to inhibiting IL-8 mediated human neutrophil chemotaxis. The mammalian expression plasmid, p6G4V11N35AchoSD.9 (identified as p6G425V11N35A.choSD is deposited as ATCC 209552). |
| 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: 200 nM methotrexate, 0.002 mg/ml recombinant human insulin, Trace Elements A (Cellgro) to a final concentration of 0.1%, Trace Elements B (Cellgro) to a final concentration of 0.1%, fetal bovine serum to a final concentration of 10%

| Subculturing |
Volumes are given for a 75 cm2 flask. Increase or decrease the amount of dissociation medium needed proportionally for culture vessels of other sizes.
- Remove culture medium. Keep the floating cells to transfer with attached cells..
- Briefly rinse the cell layer with 0.25% (w/v) Trypsin- 0.53 mM EDTA solution to remove all traces of serum that contains trypsin inhibitor.
- 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.
- Add 6.0 to 8.0 mL of complete growth medium and aspirate cells by gently pipetting.
- Add appropriate aliquots of the cell suspension to new culture vessels.
- Incubate cultures at 37°C.
Subcultivation Ratio: A subcultivation ratio of 1:3 to 1:4 is recommended
