INSTRUCTIONS DNase I, RNase-free - Thermo Fisher Scientific

1,8 • DNase I is inhibited by metal chelators, monovalent metal ions such as Na and K (i.e., ≥ 100mM NaCl), SDS even at concentrations below 0.1%, reducing agents and ionic strength above 50-100mM. • DNase I is inactivated by heating to 65°C for 10 minutes in the presence of EGTA or EDTA (use at least 1 mole of EGTA or EDTA per 1 mole of Mn

PureLink RNA Mini Kit - Thermo Fisher Scientific

RNase-free microcentrifuge pestles allow disruption and lysis of tissue samples in a microcentrifuge tube. They are usually made of Teflon, polyethylene, or stainless steel, and are designed to fit standard microcentrifuge tube sizes (e.g. conical 1.5 mL tubes or 2 mL round–bottom tubes). To use the microcentrifuge pestle: 1.

Total RNA extraction using Trizol reagent

1. Isolation of RNA from small quantities of tissue (1 to 10 mg) or Cell (102 to 104) Samples: Add 800 µl of TRIZOL to the tissue or cells. Following sample lysis, add chloroform and proceed with the phase separation as described in step 2. Prior to precipitating the RNA with isopropyl alcohol, add 5-10 •Ïg RNase-free glycogen (Cat.

Ni-NTA Purification System - Thermo Fisher Scientific

1. Equilibrate the Guanidinium Lysis Buffer, pH 7.8 (supplied with the system or see page 26 for recipe) to 37°C. 2. Harvest cells from a 50 mL culture by centrifugation (e.g., 5000 rpm for 5 minutes in a Sorvall SS-34 rotor). 3. Resuspend the cell pellet in 8 mL of Guanidinium Lysis Buffer from Step 1. 4.
