What media is used for HeLa cells?

What media is used for HeLa cells?

Culture of HeLa cells HeLa cells are maintained in Dulbecco’s modified Eagle’s medium (DMEM) containing 0.11 g/liter sodium pyruvate, 2 mM l-glutamine, 4.5 g/liter glucose, 10% fetal bovine serum (FBS), 100 U/ml penicillin, and 100 U/ml streptomycin in a humidified incubator at 5% (v/v) CO2.

How were HeLa cells cultured?

Gey’s lab assistant Mary Kubicek used the roller-tube technique to place the cells into culture. It was observed that the cells grew robustly, doubling every 20–24 hours unlike previous specimens that died out. The cells were propagated by Gey shortly before Lacks died of her cancer in 1951.

What are HeLa cells stained with?

Multiphoton fluorescence image of HeLa cells stained with the actin binding toxin phalloidin (red), microtubules (cyan) and cell nuclei (blue). HeLa cells are a cell type in an immortal cell line used in scientific research. It is the oldest and most commonly used human cell line.

Why are HeLa cells easy to culture?

Compared to normal cells, HeLa cells were shown to grow unusually fast even with their cancerous state taken into consideration. Because of their ability to multiply rapidly, HeLa cells are also capable of easily contaminating and outgrowing other cell lines in culture.

How do you split HeLa cells?


  1. remove medium.
  2. wash with PBS (~ 4 -5 ml)
  3. wash with 0.25 % Tryp./EDTA Solution (use 3 – 4 ml)
  4. trypsinize cells with 1 ml 0.25 % Tryp./EDTA sol.
  5. cells should be about 90 % confluent, if they are less confluent, use less medium to suspend them.

Are there other cells like HeLa?

There are various immortal cell lines. Some of them are normal cell lines (e.g. derived from stem cells). Other immortalised cell lines are the in vitro equivalent of cancerous cells. The origins of some immortal cell lines, for example HeLa human cells, are from naturally occurring cancers.

How do HeLa cells keep dividing?

3- HeLa cells are immortal, meaning they will divide again and again and again… This performance can be explained by the expression of an overactive telomerase that rebuilds telomeres after each division, preventing cellular aging and cellular senescence, and allowing perpetual divisions of the cells.

How long does it take for hek293 cells to adhere?

HEK-293 cells see cell doubling once every 24–48 hours depending on the care. Most HEK-293T cells double every 12–20 hours depending on conditions. Our cell doubling time is typically closer to 12 hours.

How is medium prepared for cell culture?

Dehydrated media for broth cultures need to be prepared by dissolving in distilled water and adjusting the final pH prior to sterilization. Powdered media for agar cultures must be dissolved in distilled water, stirred, then boiled or autoclaved prior to pouring into sterile petri dishes using aseptic techniques.

Can you grow HeLa cells in DMEM?

Hela Cells can be grown easily in EMEM as well as in DMEM.
