detergent enzyme lab results

A Detergent-Based Assay for the Detection of Promiscuous ...- detergent enzyme lab results ,The counter-screen relies on the detergent-sensitive nature of aggre-gate-based inhibition: molecules that inhibit an enzyme in the absence, but not the presence, of detergent are likely to be inhibiting via the formation of promiscuous aggregates. Thus, the first step of the experiment is to screen molecules for inhibition.What Are Enzyme Detergents and How Do They Work? | …Not only are enzymes natural and readily biodegradable, they allow us to clean, brighten, and whiten smarter. For instance, the enzyme cellulase helps take brightness one step further than bleaching agents by not just covering up soils but by physically removing them. Cellulases cleave off damaged micro fibrils and release any captured dirt ...
