Filter sterilize and store at +4°C. The shelf life of this solution is approximately of the cells from Step 6 (above) with 5-10 µg of linearized DNA (in 5-10 µl sterile.

A filter recognized as suitable for producing sterile filtrate is 0.2 µm pore size and capable of passing a bacterial challenge to retain a minimum of 10 7 cfu/cm² of B. dimunita. It should be noted that some samples may benefit from 0.1 µm pore size filtration, see mycoplasma reduction , to ensure a sterile filtrate for sensitive cell culture applications.

Mar 16, 2018 Cellulose nitrate (CN) filters have resulted in the highest DNA yield for all of the samples without compromising a sterile workspace too much, Regardless of the membrane filter material, always use a 0.2 µm pore size Rapid-Flow™ filters is the first choice for sterile filtration of culture media or serum . Oct 13, 2017 The 1 L aliquots were vacuum-filtered through each filter type (n = 9 filters per filter type) and stored in 5 ml sterile transport tubes (E&K Scientific) Our Scientific Applications Support team has assembled a list of frequently asked questions to help you find answers quickly. Filter using one or more categories Dec 7, 2018 However, filter paper has a weak binding affinity to plasmid DNA in least 10 min, followed by triple rinsing with sterilized water and air-drying. Plasmid DNA purification development has been driven by the increased need for large quantities of highly purified, sterile plasmid DNA for clinical studies.
