Sample Handling and Chemical Kinetics in an Acoustically Levitated Drop Microreactor

Accurate measurement of enzyme kinetics is an essential part of understanding the mechanisms of biochemical reactions. The typical means of studying such systems use stirred cuvettes, stopped-flow apparatus, microfluidic systems, or other small sample containers. These methods may prove to be problematic if reactants or products adsorb to or react with the container’s surface. As an alternative approach, we have developed an acoustically-levitated drop reactor eventually intended to study enzyme-catalyzed reaction kinetics related to free radical and oxidative stress chemistry. Microliter-scale droplet generation, reactant introduction, maintenance, and fluid removal are all important aspects in conducting reactions in a levitated drop. A three capillary bundle system has been developed to address these needs. We report kinetic measurements for both luminol chemiluminescence and the reaction of pyruvate with nicotinamide adenine dinucleotide, catalyzed by lactate dehydrogenase, to demonstrate the feasibility of using a levitated drop in conjunction with the developed capillary sample handling system as a microreactor

Egg inventory management with flock factors

Egg inventory management is critical for the poultry industry. For accurate egg inventory management, accurate projections of layer flock performance are necessary. This study found that there are some pullet flock factors that correlate with adjusted egg production percentage, which may assist in developing an accurate egg production projection system. Previous research has not included how to predict base off of early flock performance indicators. This approach will allow for more accurate projections and better egg inventory management. Due to the size of the sample utilized for this study, it is recommended that further study is conducted to verify findings
