The phrase "a very low activity" is correct and usable in written English.
It can be used to describe a situation or condition where the level of activity is minimal or significantly reduced.
Example: "During the winter months, there is often a very low activity in the local tourism sector."
Alternatives: "minimal activity" or "slight activity".
The construct containing the 100 bp upstream of the arbitrary zebrafish TSS (z100 bp) has a very low activity, about 15% of the enhancerless SV40 promoter, but is activated about 10-fold when associated to the zebrafish (zE) enhancer.
Mutations of these aforementioned four aspartates to alanine or asparagine inactivated the enzyme, except for D357N, which resulted in a very low activity (Fig. 4c).
On the other hand, Pt/C shows a very low activity, this certifying the determinant role of ceria in this reaction.
It appears that the oxidation state of titania played a critical role in photocatalytic activity given that partially reduced coatings resulted a very low activity.
On the bulk palladium single crystal electrodes, NO formation leads to a fast blockage of the surface resulting in a very low activity for nitrate reduction.
In general, modified methylaluminoxanes (MMAOs) and methylaluminoxanes (MAOs) were found to have similar activities, whereas isobutylaluminoxane (IBAO) gave a very low activity in the polymerization of ethylene.
Scoring of transfected cells categorize BRMS1-NES as a functional, very low activity signal, as efficient as p53 and HDM2, but less active than proteins which completely shift the GFP-fusion protein in the absence of Act-D.
Monomeric ribonuclease A has very low activity toward typically double-stranded RNA's; the dimeric form of ribonuclease A obtained by cross linking the enzyme by dimethyl suberimidate has more than 78 times the activity of the monomer toward polyadenylate · polyuridylate and 440 times the activity of the monomer toward the double-stranded RNA of a virus from Penicillium chrysogenum.
"If the sun went into a state of very low activity, it's possible, but unlikely," says Haigh. "There's no way of forecasting the sun so I wouldn't hold your breath".
Substitution of Asp for Asn yielded an acidic ChiB mutant, with very low activity at pH 7, but significant (wild-type like) activity at pH 4.5 [ 9].
The problem seems to be inherent in the TALEN design, as this pair also showed very low activity in a yeast assay (data not shown).
