HeLa Cell Pellets
$290,00 – $540,00
Hela cells pellets harvest in exponential phase.
The HeLa cell line was established from an adenocarcinoma of the cervix in 1952. It is the first continuous human cell line.
Cultures are screened for the presence of bacteria, yeast, fungi and mycoplasma (DNA amplification). NBCS used in the culture medium is certified from New Zealand origin.
HeLa cells Production
HeLa cells are grown in sonoperfused fedbatch (cytostat) mode at a constant concentration of 5×106 cells/ml (cell viability: 93%-99%) under GLP conditions in our facility in Mons, Belgium. Cells are harvested in exponential phase.
Cell pellets are prepared by low speed centrifugation, rinsed with phosphate-buffered saline, snap frozen in liquid nitrogen and stored at -85°C.
The cell pellets are not prepared in aseptic conditions and are not intended to be used as seed for a new culture.
Our HeLa cell pellets are used by research or production entities worldwide for the study of biochemical processing, high throughput screening or purification of biological material from human origin.
Also suitable for use in:
entities production and purification of biological material from human origin used in many other applications;
isolation of gDNA and RNA;
fixation of the pellet;
production of whole cell lysates;
