K-TEK DNA Test Sample
DNA01 is Plasmid pGem7zf+ (Promega), which is linearized with the SmaI endonuclease. Linear DNA molecules (3000 b. p.) are deposited at the freshly cleaved mica. Molecules are uniformly distributed over the surface with the molecular density - 0,5-7 molec./um2. The typical DNA length is 1009 nm. Recommended humidity for obtaining a good image is 3-5%.
K-TEK Nano DNA Sample is perfect for:
- Beginners learning tool for AFM
- Teaching applications
- Estimation of cantilever / probe tip curvature
- Humidity test
- Z-resolution tests
- Example of how to prepare your own DNA samples
