An immunoassay is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody or an antigen. Immunoassays come in many different formats and variations, and may be run in multiple steps with reagents being added and washed away or separated at different points in the assay.

It is increasingly recognized that the genetic background (i.e., all genomic sequences other than the gene(s) of interest) can have profound influences on the phenotype of an animal model. I...
With the growth and expansion of mouse and rat transgenic models in recent years, the demand for surgically altered models mimicking human diseases is growing at an amazing rate. Surgical pro...
Nonhuman primates in captivity are typically provided with a multitude of behavioral management opportunities, including naturalistic social groupings, foraging devices, complex physical envi...
