By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.

Human monocyte-derived dendritic cells are generated by isolating PBMC-derived monocytes and culturing them with GM-CSF plus IL-4, which produces cells with dendritic-cell antigen-presenting properties, reduced monocyte phenotype, and increased dendritic-cell functional readouts such as antigen uptake, allogeneic T-cell stimulation, and expression of markers including HLA-DR, CD80, CD86, CD83, CD1a, or CD209 depending on protocol and maturation state. The main readout is phenotypic and functional differentiation: immature MoDCs are commonly evaluated by loss or reduction of CD14 with acquisition of dendritic-cell markers and antigen uptake capacity, whereas mature MoDCs are evaluated by increased CD83, CD80, CD86, HLA-DR, and T-cell stimulatory function after exposure to maturation stimuli such as TNF-α or a cytokine/PGE2 cocktail.
