Validation of salivary cortisol and testosterone assays in chimpanzees by liquid chromatography‐tandem mass spectrometry
Owing to its high temporal sensitivity, saliva has distinct advantages for measuring steroids, compared with other noninvasive samples such as urine and feces. Here, we report the validity of assaying salivary cortisol (C) and testosterone (T) using liquid chromatography‐tandem mass spectrometry (LC‐MS/MS) in captive male chimpanzees, Pan troglodytes . For both the C and T concentrations, we found positive relationships between saliva and plasma.…
Presenilin-2 in the cynomolgus monkey brain
Familial early onset macular degeneration in cynomolgus monkeys ( Macaca fascicularis )
Collection and analysis of hematopoietic progenitor cells from cynomolgus macaques ( Macaca fascicularis )
Previous studies have shown that hematopoietic progenitor cells can be isolated from human or nonhuman primate bone marrow (BM) cells. In the present study, we studied the cross‐reactivity of 13 anti‐human CD34, two anti‐human c‐Kit, and one anti‐human CD133 monoclonal antibodies (mAbs) with cynomolgus macaque ( Macaca fascicularis ) BM cells, using flow cytometric analysis, cell enrichment, and clonogenic assay. Among the 13 anti‐human CD34 mAbs…

A two‐step extraction method to measure fecal steroid hormones in female cynomolgus monkeys (Macaca fascicularis)
We developed a two-step extraction method for measuring fecal steroid concentrations. In the first step, distilled water was used to extract steroids from fecal samples. In the second step, a mixture of organic solvents (hexane and ether) was used to re-extract water extracts that had been transferred to a glass tube. A portion of the upper layer of the organic solvents was transferred to separate assay-tubes for measurement of estradiol (E2) or …
