To accomplish the former MMC was loaded onto oxidized sulfopropyl dextran microspheres, released in a pH 7.4 buffer solution and tested for its potency against EMT6 cells versus a standard MMC solution.
Five millilitres of the combined column fractions containing recombinant proteins were dialysed against 80 mM sodium phosphate buffer pH 6.8 and tested for chitinolytic activity.
To further test for E. coli contamination, nematodes were removed 24 h post infection; pathogen-containing lawns were harvested, diluted appropriately in M9 buffer (Brenner, 1974) and tested for E. coli and B. thailandensis by plating on neat LB agar and LB agar supplemented with gentamicin 25 μg ml−1 (Thermo Fisher Scientific Waltham, MA).
After infection, HIGK were harvested, lysed on ice in sterile filtered lysis buffer for 30 min and tested for levels of caspase 3 activity using a 7-amino-4-methylcoumarin (AMC) release assay (BD Pharmingen) and following the manufacturer's protocol.
Remove and test for odor.
Likewise, release of adenoviruses from spots was not observed when the washing buffer was tested for infectious particles (data not shown).
After fixing, cells were rinsed with buffer B (3.3 mM K3Fe CN 6, 3.3 mM K4Fe CN 63H2O in buffer A), and then tested for β-gal activity by incubating with the substrate X-gal (0.3% X-Gal in buffer B) at 37°C in dark for 3 hours.
Prior to any stimulation all ligands, buffers, and media were tested for LPS content, which could influence the levels of background cytokine secretion.
After initialization, the chip was washed with 100% isopropanol and annealing buffer (from sequencing kit) and then tested for its functionality on the PGM.
Mice were injected intraperitoneally with streptozotocin (Sigma, 195 mg/kg) or vehicle (citrate buffer 0.1 M, pH 4.5) and were tested for glycosuria 48 h later using Keto-Diastix (Bayer Diagnostics, Argentina).
