The saliva samples were then placed on ice, supplemented with EDTA-free Protease Inhibitor Cocktail (Roche Applied Science, Switzerland) prior to centrifuging at 10000 x g for 15 min at 4 °C.
Cells were harvested in Tris lysis buffer on ice supplemented with 1% (v/v) Triton X-100 and protease inhibitors and homogenized 10 times with a Dounce homogenizer and centrifuged at 200 × g for 10 min.
1 ml blood was mixed with 1 ml buffer (phosphate-buffered saline, 0.1% bovine serum albumin, 0.1% sodium azide, and 0.6% sodium citrate) on ice, supplemented by 20 μl of FcR-blocking agent (Miltenyi, Bergisch Gladbach, Germany) and 50 μl anti-CD 146-coated Dynabeads (10 μg ml-1).
The spheroplast suspension was transferred onto ice, supplemented with 100 μg/ml AMT psoralen (4′-aminomethyl-4,5′,8-trimethylpsoralen 4′-aminomethyl-4,5′,8-trimethylpsoralen 4′-aminomethyl-4,5′,8-trimethylpsoralen 4′-aminomethyl-4,5′,8-trimethylpsoralenotal RNA was extracted from tHRI Associates Inc .plasts.
Samples were transported in dry ice under continuous temperature measurements and access to dry-ice supplements.
The script uses, to the extent currently available, climate-independent volcanic synchronization of these two ice cores, supplemented by oxygen isotope alignment.
Peter and I had been living on two hours sleep a night and enormous quantities of apple pie and ice cream supplemented by the offerings of gentle-faced strangers, who would turn up at the front door with legions of homemade vegetable pies and lasagna.
Briefly, a sporulated colony was heat-shocked in 10 ml of 2 × YTG medium, cooled on ice, and supplemented with 10 μg ml−1 thiamphenicol (Sigma-Aldrich; St .Louis, Missouri, United States).
Cells were then thawed on ice and supplemented with a mixture of protease inhibitors (aprotinin 2 μg/ml, benzamidine 15 μg/ml, leupeptin 2 μg/ml, PMSF 1 mM, pepstatin A, 1 μg/ml).
The mixture of 5 μg of total RNA and random primers (400 ng μl−1) was heated for 10 min at 70°C, cooled quickly on ice and supplemented with 0.5 m M dNTPs (Finnzymes), reverse transcriptase buffer containing 6 m M MgCl2, 40 m M KCl, 1 m M DTT, 0.1 mg ml−1 BSA, and 50 m M Tris HCl, pH 8.3.
Following heat inactivation of Mbo I at 70°C for 10 min, each tube was chilled on ice and supplemented with 50 μl of ligation buffer (100 mM Tris-HCl, pH 6.9/4 mM ATP/4 mM DTT/10 mM MgCl2) and 100 pmol of an adaptor mix (Table 2).
