After adding about 50% of the total volume of diluent and ultrasonicating for about 15 to 20 min, the solution was made up to the mark with the diluent and filtered through Merck nylon syringe filter (Merck KGaA, Darmstadt, Germany) having pore size 0.45 μm.
For RNA dilution experiments, 2 μL of RNA diluent (total RNA control (human), Applied Biosystems) was prepared by serial dilution to concentrations of 52, 35, 17, 7, and 1.4 pg/μL in 10 mM Tris buffer, pH 8.0 (1 M Tris, pH 8.0, Ambion, Carlsbad, CA, diluted with UltraPure DNase/RNase-free water, Invitrogen).
For estimation of cAMP levels, the untreated scrambled and MVI-KD cells were cultured for 48 h and then washed twice with PBS, dissolved in sample diluent of total cAMP enzyme immunoassay kit (Biotrend, Germany), and the further procedure followed the supplier protocol.
Metformin (Sigma, St . Louis MI, USA) was dissolved in cell culture medium and was administered at a dose of 50 mg/ kg every other day by intraperitoneal injection, with the appropriate diluent made up to a total volume of 200 μl.
In contrast to inert gas dilution, a total pressure decrease also reduces the need for a diluent gas, thus simplifying the process and avoiding energy penalties associated with inert gas recycling.
Two millilitre aliquots of C. raciborskii cultures were collected and harvested by centrifugation in 2 mL Eppendorf plastic tubes at 11000 g for 15 min. All sampled pellets were resuspended in 0.5 mL of diluent flame solution and immediately analysed for total Na+- K+ cellular content using a FLM3 Flame Photometer (Radiometer, Copenhagen, Denmark).
In brief, 50 μl of assay diluent and known quantities of samples (15 30 μg total tissue homogenates) and controls (0 500 pg/ml mouse IL-6 standard, supplied by the company) were loaded onto a microplate pre-coated with mouse IL-6 specific antibody.
A total of 100 μL of the sample (CSF Diluted 1 3 with Sample Diluent) was used in each reaction.
Vaccine strains and negative controls were administered subcutaneously in a total volume of 0.5 mL iodixanol solution (33% in phosphate-buffered saline diluent).
HONIARA, 15 September 2014 - Following efforts by the Ministry of Health and Medical Services (MHMS) and other partners to accelerate a nation- wide measles campaign, UNICEF this week air lifted to Honiara a total of 50,000 doses of Measles and Rubella (MR) vaccines with diluents worth $277,970 SBD $38,0000 USD).
