Western blot

Southern blot

Reverse transcription polymerase chain reaction (RT-PCR)

Immunocytochemical analysis

Enzyme-linked immunosorbent assay (ELISA) RT-PCR is the only method to quantify the level of mRNA inside the cells. The western blot is an assay to detect protein expression level inside the cells. ELISA is a biochemical technique used mainly in immunology to detect the presence of an antibody or an antigen in a sample. Immunocytochemical analysis is a technique to stain cells using antibody to localize a certain protein within the cells. Southern blot is a technique to detect genomic DNA expression of a certain gene.
