Metabolic competency of in vitro systems is a key requirement for the biotransformation and disposition of drugs and toxicants. In this protocol, we describe the application of reference metabolic probes to assess phase I metabolism in cell...

Emission Spectra

Emission Spectra

When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

A Turbidimetric Analysis to Monitor Collagen-Induced Aggregation of Pretreated Human Platelets

This video demonstrates turbidimetric analysis to assess collagen-induced platelet aggregation in pre-treated, washed human platelets. Control wells show collagen-induced aggregation, whereas a high concentration of inhibitors blocks Pannexin-1 channels, thereby inhibiting collagen-induced platelet aggregation, evident from unchanged...

Induction and Assessment of Class Switch Recombination in Purified Murine B Cells

Induction and Assessment of Class Switch Recombination in Purified Murine B Cells

Following antigen exposure, subpopulations of activated B cells undergo a process known as class switch recombination (CSR) to produce antibody isotypes with distinct effector functions. The protocol outlined in this report explains how CSR can be induced and analyzed in vitro for the purposes of studying B cell...
