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.
3

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

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.

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.
12

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

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.
17

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.
