3. CELL LINES
The culture produced by the cell or tissue
taken from an organism is termed as primary
culture.
Cell line implies to the sequence of culture
obtained from the sub cultivation of the
primary culture.
A cell line is a product of single layer cells that
are used for biological research.

4. PRIMARY CULTURE
Directly from cells or tissues.
Collagenase or trypsin – breakdown
extracellular matrix.
Media is supplemented.
Incubation and growth.

9. HANDLING OF CELL LINES
Cell lines may be contaminated with
microbes.
They should be handled in accordance with
OSHA (Occupational Safety And Health
Administration).
Personal protective equipment outer wear
like gloves, gowns, face masks etc. should be
used.

12. MAINTENANCE OF CELL LINES
Cell lines are grown as monolayer in culture
vessels.
They are either maintained under continuous
illumination or in the dark.
The standard growth conditions for all cell lines
are
24 °C - 37o
C and 40 % rel. humidity
Two independent sets of the whole collection are
maintained independently.
Maintaining of cell lines is done by passaging.

16. CO2 INCUBATOR
Maintains temperature, humidity,
CO2, O2 contents.
Adjustable heaters – maintain temperature.
Incubator shelving is
perforated – circulation
of air.

17. INVERTED PHASE MICROSCOPE
Views objects from an inverted position.
Views live specimens.
Views living cells at the bottom of a large
container than on a glass slide.

18. STORAGE OF CELL LINES
Cryopreservation:
Preservation at low temperatures
Generally solid CO2 and
liquid Nitrogen are used.
Cryoprotectives are also used.
Most commonly used cryoprotectives
are DMSO and glycerol.
