CRL-2843   3D4/21  豬肺泡巨噬細胞

Strain  Landrace

Applications

These porcine myelomonocytic cell lines may have a wide variety of applications in porcine virology and immunology Ref.

Storage Conditions  liquid nitrogen vapor phase

Derivation  The parental porcine monomyeloid cell line, 3D4, was established in December of 1998 following transfection of primary porcine alveolar macrophage cultures with the pSV3neo plasmid.

Single cell cloning and selection in G-418 of the 3D4 parental cell line resulted in establishment of 3D4/2 (ATCC CRL-2845), 3D4/21 (ATCC CRL-2843) and 3D4/31 (ATCC CRL-2844).

Virus Susceptibility  Bovine adenovirus 3

Classical swine fever virus , Classical swine fever virus

Human parainfluenza virus 3

Swinepox virus

Vesicular stomatitis New Jersey virus

Porcine adenovirus

Herpes simplex virus 1

African swine fever virus

Pseudorabies virus

Vaccinia virus

Comments

The plasmid carries the genes for neomycin resistance and SV40 large T antigen.

A subpopulation of each cell line (3D4/2 (ATCC CRL-2845), 3D4/21 (ATCC CRL-2843) and 3D4/31 (ATCC CRL-2844)) was positive, to varying degrees depending on the media formulation, for nonspecific esterase activity and phagocytosis.

Clone 3D4/21 can produce Bovine adenovirus type 3 (BAV-3) to markedly higher titers than clones 3D4/2 and 3D4/31.

Addition of DMSO improved the capability of clone 3D4/21 to replicate the field isolate of African swine fever virus (ASFV/Lillie) compared to the other clones.

Complete Growth Medium  RPMI 1640 medium with 2 mM L-glutamine adjusted to contain 1.5 g/L sodium bicarbonate, 4.5 g/L glucose, 10 mM HEPES, 1.0 mM sodium pyruvate supplemented with 0.1 mM nonessential amino acids, 90%; fetal bovine serum, 10%

Subculturing

Volumes used in this protocol are for 75cm2 flasks; proportionally reduce or increase amount of dissociation medium for culture vessels of other sizes.

Remove and discard culture medium.

Briefly rinse the cell layer with 0.25% (w

) 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. An inoculum of 5 x 103 to 7 x 103 viable cells/cm2 is recommended.

Incubate cultures at 37°C. Subculture when cell concentration reaches between 3 x 105 and 4 x 105 cells/cm2.

Subc*tion Ratio: A subc*tion ratio of 1:6 to 1:8 is recommended

Medium Renewal: Two to three times weekly

Note: For more information on enzymatic dissociation and subculturing of cell lines consult Chapter 13 in Culture Of Animal Cells: A Manual Of Basic Technique by R. Ian Freshney, 5th edition, published by Wiley-Liss, N.Y., 2005.
