HeLa lysates (lysis buffer: 1% NP-40, 10-mM HEPES (pH 7.4), 150-mM KCl, 5-mM MgCl2, 0.25-mM DTT, 50-μM cycloheximide, 0.4-U/μl RNAsin and protease inhibitors) were pretreated with cyclohexamide and spun down (10,000 g, 10 min, 4°C), and equivalent amounts of supernatant were layered onto a 0.5-M sucrose cushion.
Proteins were denatured in 1× Laemli buffer at 95°C for 10 min and an equivalent of 2×10 cells per well comb were loaded on a polyacrylamide gel.
After cooling, the reaction mixture was centrifuged at 6,000 × g for 10 min, and TBARS equivalent in supernatants monitored at 532 nm.
Samples were then mixed with Laemmli sample buffer (62.5 mM Tris HCl pH 6.8, 2% SDS, 10% glycerol, 5% β-mercaptoethanol, 0.001% bromophenol blue), boiled for 5 min and the equivalent of 1 x 10 to 5 x 10 PFU/lane were run on a 10% Tris-glycine SDS-PAGE gel by standard methods [ 35].
Lysates were pre-cleared by centrifugation at 10000 rpm for 10 min at 4°C and equivalent protein amount (500-700 µg) was incubated overnight at 4°C with anti LIMK1 or anti MAPKAP-2 polyclonal antibodies.
On the other hand, the EEASs we observed had several properties that were different from those of omega bands, such as greater eastward propagation speed (3 4 km/s), shorter associated magnetic pulsation periods (4 6 min), and a different ionospheric equivalent current direction.
In both cases, nutrient repletion was accomplished by pelleting in a Beckman J6 centrifuge at 30° at 2500 rpm for 5 min and resuspension in an equivalent volume of fresh SD medium.
To prepare individual spiked standards, plasma was thawed for 30 min, different concentrations of latrunculol A were added to 200 μL of plasma samples and acetonitrile was added to each a total volume of 1 mL, vortexed for 1 min, and centrifuged at 14,000 rpm (equivalent to 19,280× g) at 4 °C for 25 min.
Whole cell extracts were appropriately diluted in 3 X concentrated electrophoresis sample buffer and boiled for 10 min. Equivalent amounts of protein (100 or 50 μg) were loaded in fixed 7.5% or 12% polyacrylamide gels, subjected to SDS-PAGE and transferred to PVDF membranes.
Considering maximization of the enzymatic hydrolysis yield as optimization criterion, results show that 87% of the glucose content in the raw material can be released by enzymatic hydrolysis at 202 °C, 5 min and 0.32% H3PO4, which is equivalent to 41.1 g sugars/100 g rapeseed straw.
