Primary human cells are cells that are directly cultured from their source organ tissue.
Your experimental outcomes will be true: Primary cells are directly cultured from their source organ tissue and have not been modified in any way. This helps avoid altering the outcome of your experiments.
Your research outcomes will be more representative of the general population: Primary cells can come from many donors. Having a variety of primary cell types from many different donors (young, old, male, female, different ethnicities, etc.) is especially useful when carrying out early drug testing. This helps ensure that the drug is effective for everyone.
Your experimental results won’t be negatively impacted: Lifeline cells have not been exposed to antimicrobials or phenol red, components which can cause cell stress and “masking effects” that may negatively impact experimental results.
Especially appropriate for accurate results using reproductive cells: If reproductive cells are exposed to phenol red, it can act as a weak estrogen and may stimulate estrogen receptors. This can cause masking effects that could negatively affect studies with human female reproductive cells. Lifeline cells are not exposed to phenol red.
