Subculture of continuous cell line– monolayer
culture
Construction and analysis of growth curve
Advanced Techniques
Detection of mycoplasma
Cell line characterization and analysis
Primary Culture
Cytotoxicity assay
Exercise 1. Aseptic Technique
Purpose:
Practice in transferring fluid from one bottle to another
Exercise 2. Aseptic Technique
Purpose:
Preparation of Buffers and Culture medium and
Procedures :
1. Preparation of 10XPBX
2. Preparation of DMEM+ FBS+ Penicillium/Streptomycin
3. Sterilization of bottles and pipettes and equipments
Exercise 3. Cell Line maintenance and cell passage
General procedure for the cell culture laboratory1. Thawing cells
Culture of cell lines( frozen stock) Thaw Cell line maintenance
Day 1 frozen culture( -190oC) 1 ml in frozen medium 37oC, thaw Add, 10ml culture medium( DMEM+FBS+p/s)
1200 rpm, 5 min
Remove suspension resuspend cell pellet with 5 ml growth medium plating 106 cells/ml
Day 2
Culture( cells checked under inverted microscope)
Remove culture medium, Replace with fresh culture medium (3ml)
Day3 subculture remove culture medium cells washed with 2ml CMF/PBS remove PBS cells, trypsinize with 1x trypsin( 0.025%) ( flush cell by pipetting repeatly) cells taken into 15ml centrifuge tube
1200 rpm, centrifuge, 10min trypsin, removed add 5 ml DMEM cells diluted for plating( 1/4 dilution) in 6 mm cullture dish 37oC, CO2 incubator
2 to 3 days later
cells trypsinize with 1x tyrpsine ( protocols follow the previous page ) cells, resuspend with 5 ml DMEM cell, 10 ul was taken+ 10ul trypane blue cell counting
