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 Aim. Adherent cell lines will grow in vitro until they have covered the surface area available or the medium is depleted of nutrients.At this point the cell lines should be subcultured or passaged in order to prevent the culture dying. To subculture the cells they need to be brought into suspension. The degree of adhesion varies from cell line to cell line but in the majority of cases. 3. For monolayer cells: Rinse the monolayer cells 3 times with cold PBS. For the final rinse, use a cell scraper and transfer the cell suspension to a TPX tube. Centrifuge cells at 1,500 rpm for 10 min at 4°C and aspirate as much supernatant as possible. Proceed to step 4. For suspension cells Approximately 2mL per 10cm2 cultured surface area. Gently add wash solution to the side of the vessel opposite the attached cell layer to avoid disturbing the cell layer. Gently rock the vessel back and forth several times to wash the cell layer. Remove and discard the wash solution from the culture vessel Recently, I have started seeing some cell clumps in my culture of HeLa cells. I thawed a fresh batch of cells and they also have it.

HeLa cells have been cultured continuously for scientific use since they were first taken from the tumor of a woman suffering from cervical cancer in the 1950s. They have been utilized for many purposes, including the development of a polio vaccine, the pursuit of a cure for diseases such as leukemia and cancer, and the study. HeLa cells are the archetypal tissue culture cell line for the preparation of mammalian cell-free systems. These cells, derived from a cervical carcinoma, have been maintained in culture since the late 1940s. They grow with a doubling time of ∼24 h and can be cultured in medium containing fetal bovine serum (optimal serum for growth) or.

The cells need to be passaged or plated when a plate reaches ∼70% confluency. A detailed mammalian cell culture protocol can be found in Phelan . The estimated experimental time on Day 1 is 2 hr. Passaging HeLa cells. 1. Aspirate the cell culture medium from a T-75 flask containing growing HeLa cells. 2 Staining protocol 1. Discard the cell culture medium by inverting the slide and gently tapping it on a paper towel to remove the remaining medium. 2. ™Fix the cells with 4% formaldehyde (diluted in 1X PBS— prepare fresh) for 10 min at room temperature (fixation time can be increased to 20 min depending on the cell line)

Immunocytochemistry Preparation & Fixation Protocol. Culture cells by adding 500 µL of culture media containing approximately 5000 cells to the wells of a cell culture plate containing gelatin-coated coverslips.; When cells have reached the desired density/age, remove the culture media from each well and wash twice with PBS.; Add 300-400 µL of 2-4% Formaldehyde Fixative Solution to each well. Once a cell culture has been started, it cannot be grown indefinitely due to the increase in cell number, consumption of nutrients and increase in toxic metabolites which eventually results in cell death. Moreover researchers usually want to perform experiments on their cells several times, and therefore do not want to use up all of the cells at once Stable transfectants of HeLa cells were generated as described previously (Storrie et al., 1998). Briefly, plasmids encoding GalNAc-T2 GFP or GalNAc-T2 CFP were transfected into HeLa cells cultured in 10 cm tissue culture dishes in the presence of 5% FCS using the calcium phosphate protocol (Paabo, Weber, Nilsson, Schaffner, & Peterson, 1986)
