Technique used in Molecular Biology
| 1 | Northern blot | Study gene expression by detection of RNA |
| 2 | Western blot | used to detect specific proteins |
| 3 | Eastern blot | analyze protein post-translational modifications including the addition of lipids, phosphates, and glycoconjugates. |
| 4 | Southern blot | Study gene expression by detection of DNA |
| 5 | Southwestern blot, | study DNA-protein interactions |
| 6 | Northwestern blot | Study RNA -proteins interactions |
