The 3,3-diaminobenzidine (DAB -positive substrate was useDAB -positiveor reaction.
Thus, substrate fingerprints revealed that V12_26 (33 positive substrates) exhibited the widest substrate range.
However, a priori biochemical knowledge on the signs of the elasticities is available, i.e. elasticities are positive for substrates and negative for products.
Therefore, we argue that LSE genes are a much more important substrate for positive selection to act on than single-copy genes.
Furthermore, work by Mitchell (1976) showed that Salvinia has a positive effect in providing a substrate for fish food organisms and cover for several species at a time when submerged macrophytes were sparse.
Regarding selection of positive training sets, substrates for which there were multiple lines of evidence from different sources were given preference.
Following incubation with 3,3-diaminobenzidine hydrochloride (DAB, Sigma, Poole, UK) as a substrate, positive staining for the presence of iNOS was seen as a dark brown end product.
In these examples, a terminal α1,2-linked mannose residue on the b- or c-branch of Man9GlcNAc2-PP-Dol is a positive determinant for substrate selection by the T. cruzi OST, whereas E. histolytica and T. vaginalis OSTs select donors with a non-glucosylated a-branch in the LLO but do not discriminate between Man5GlcNAc2-PP-Dol and Man9GlcNAc2-PP-Dol (Kelleher et al. 2007).
After final washing, the GNA-positive proteins were visualized using NBT/BCIP solution as substrate for AP.
The new fluorescent CDK inhibitors showed undiminished activity in multidrug resistance (MDR) positive breast cancer cells, indicating that they are not a substrate for p-glycoprotein.
