Moreover, in some cases these reagents can differentiate between the active and inactive forms of the enzyme, indicating that they are activity-based probes.
Because the assay is activity-based such that the toxin is detected through the enzymatic cleavage of target proteins, it is critical to include in the extraction step antibodies that do not hinder the activity of the toxin.
An alternative is activity-based costing.
One technology that has arisen to meet this challenge is activity-based protein profiling (ABPP) that uses activity-based chemical probes to broadly assess the functional states of both characterized and uncharacterized enzymes.
But a handful of the new update features are activity-based, letting users tell friends what they're "listening to," "reading," "drinking," "watching" or "eating".
One particular cost accounting methodology is activity-based costing (ABC).
An exciting experimental platform to explore this possibility is activity-based profiling.
Activity-based learning One of the success stories of the post-tsunami effort, and an important aspect of the education package, is activity-based learning (ABL).
Furthermore, the definition of disability has, over the years, changed from being impairment-based to being activity-based, with direct consequences on operationalisation and screening for disability [ 7].
An emerging and powerful approach is activity-based protein profiling (ABPP), a chemical biology probe-based technology that can reveal details of microbial catalytic and regulatory functions for bioenergy-relevant applications.
An aspect of upstream analysis that makes it especially powerful is that it is essentially an activity-based prediction, in that the measurement of the activity of a transcriptional regulator is via the measurement of genes known to be differentially expressed by it in a defined direction.
