Sephacryl-300 (Pharmacia) was poured into a 20×1 cm glass gel filtration column (BioRad) and packed using gel filtration buffer (0.1 M NaPO4, pH 7.4, containing 0.15 M NaCl) at a flow rate of 1 ml/min.
To avoid loss of any cell during the washing process, the washing solution was passed through a glass cup filtration system including a filter of 0.22 μm pore-size.
Control tests demonstrated that no sorption occurred on either glass or filtration frameworks.
The Boost heats to an optimal temperature with a simple button press, making it one of the easiest dabbing solutions available, and when attached to the included glass water filtration piece, the Boost replicates the dabbing experience perfectly.
The nucleic acid isolation in SeptiFast test protocol includes successive steps of mechanical/enzymatic lysis and glass fiber filtration and is a mostly hands-on procedure for extraction that takes 3.52 hrs.
[8] for reporting, furthermore, SeptiFast test currently uses a manual extraction procedure based on mechanical/enzymatic lysis and glass fiber filtration that involves extensive time (up to 211. 4 min) and labor, There are currently a number of choices for automating this process [16], [17].
DNA was extracted from blood, muscle or liver by phenol, chelex or a membrane purification procedure with glass fiber filtration plates (Acroprep 96 Filter Plate- 1.0 μm Glass, PALL Corporation [ 38]).
DNA extraction of blind‐test samples followed a silica‐based method utilizing multichannel pipettes; PALL glass fiber filtration plates; and buffer, centrifuge and transfer protocols described in Ivanova et al.
The powdered tissues were incubated with 2x CTAB buffer at 65°C for 1 hour and DNA was then extracted using semi-automated method employing glass fiber filtration [ 45, 46].
When it was determined that greater than 90% of cells were infected, host cell free Ap were prepared by needle aspiration, 2.0 μm glass fiber filtration (Whatman), and twice washed in 270 mM sucrose.
