Characterization of the colon digests consisted of determining As bioaccessibility and As speciation.
Sham digest controls consisting of DNA free water were processed with every extraction run serving as negative controls to monitor for fungal contamination.
The pretreated (acid digested) MWCNTs consists of carboxyl groups in the backbone that can bind with Cu2+ and Ag+ ions very easily, especially with these bio-capped MNPs.
The restriction digestion of PI 468916 to create the RRL consisted of digesting a total of 50 μg of DNA with the combination of 30 units of HaeIII, 15 units of PsiI, 15 units of SspI, 30 units of RsaI, and 15 units of MslI.
Indeed, the second step consisted of digesting the EYFPBax cDNA by NheI/SmaI enzymes from the pEYFP-C1 vector (Clontech, USA) followed by a Klenow blunting and cloning of the fragment into the pBI-Tet vector from the first step previously digested by SalI (blunted).
The first tier restriction consisted of digesting Jalo EEP 558 DNA with three restriction enzymes followed by gel size selection of the 300 to 350 bp DNA fragments.
DNase digest buffer (10×) consists of 0.5 M Tris-HCl pH 7.5 supplemented with 0.5 mg/ml BSA.
Chondrocytes were isolated by digesting cartilage in digestion media consisting of 500 ml 1 1 Dulbecco's Modified Eagle Media (DMEM):F-12 (Hyclone), 50 ml Fetal Bovine Serum (FBS) (Axenia BioLogix, Sacramento, California), and 100 mg collagenase-P (Roche, Mannheim, Germany).
Sarcomas were removed after animals were sacrificed and the tumors were digested with tissue digestion buffer consisting of 5 mg/ml collagenase IV (Sigma-Aldrich, St Louis, MO), 2.5 U/ml dispase (BD Biosciences, Franklin Lakes, NJ) and 0.05% trypsin (Life Technologies, Carlsbad, CA) at 37°C for 40 min.
