Then, slowly, under constant stirring, an equal amount of saturated ammonium sulphate was added.
(By the way, a batch of simple syrup, made by stirring sugar in an equal amount of water until it dissolves, is a handy thing to keep around in hot weather).
The high molecular weight (HMW) fraction was prepared by the classical 2-step desolvation technique, where 5% (w/v) gelatin type "A" was first desolvated with an equal volume of acetone for 12 minutes under gentle stirring.
300 µl washed platelets (5×108/ml) were stimulated under stirring conditions (1200 rpm), terminated by addition of an equal volume of ice-cold 2% NP-40 lysis buffer and immunoprecipitations (IPs) carried out as previously described [28].
Dispersed stock suspensions of SWCNTs were prepared by stirring in sodium dodecyl sulphate (SDS), an anionic surfactant, on an equal w/w basis.
The reactants were mixed with an equal weight of xylene and heated gradually to 150 ± 5 °C with continuous stirring for about 4 h using a well-controlled thermostat.
This is followed by addition of an equal volume of 2.4633 g of ammonium metatungstate to maintain stoichiometric ratio (1 1) with continuous stirring.
Briefly, an equal volume of FePt@SiO2 (183 mg/mL) and acetic acid were mixed with EDS under vigorously stirring for 1 h at room temperature which will resulted in amine-functionalized FePt@SiO2 (FePt@SiO2-N).
A equals a equals a equals a equals a.
It is always advisable to first mix the required amount of concentrate with an equal volume of water, and then add the resulting slurry to perhaps another 25 litres of water, stirring all the time.
