Improved CZE capabilities with new dynamic coatings.

Electroosmotic flow (EOF) is one of the fundamental processes affecting both resolution and separation times in capillary zone electrophoresis (CZE). EOF is a function of pH and buffer composition (zeta potential) in bare-silica capillaries at any pH above 3 and runs in the cathodal direction, decreasing the effective separation length for cationic species. On the other hand, the absence of EOF at low pH can significantly increase separation times, particularly for low pl zwitterionic species.

Rapid separation of protein isoforms by capillary zone electrophoresis with new dynamic coatings.

Many cellular functions are regulated through protein isoforms. Changes in the expression level or regulatory dysfunctions of isoforms often lead to developmental or pathological disorders. Isoforms are traditionally analyzed using techniques such as gel- or capillary-based isoelectric focusing.

Data initiatives: building a managed care network utilizing clinical performance data.

Responding to the rising health care costs of its traditional indemnity health care plan, Hershey Foods Corporation developed its own managed care plan as part of the company strategy to better control its health care costs. In developing a provider network for its managed care plan, Hershey Foods utilized data from the Pennsylvania Health Care Cost Containment Council and the expertise of many different groups, health care data consultants (Healthcare Research Affiliates), the insurance provider (Capital Blue Cross/Pennsylvania Blue Shield), health care providers, as well as the employees and their union representatives. Selection of providers for the network necessitated a data initiative that analyzed indicators of quality and cost efficiency.
