Giardia Ag Rapid Test (RAP-5407 and RAP-5408) chromatographic immunoassay is a procedure for in vitro qualitative detection of Giardia antigens in stool samples. Giardia intestinalis, also called Giardia lamblia, is a gastrointestinal protozoan parasite infecting various species (mammals, birds, etc.). It causes a clinical picture that ranges from the symptom-free carrier to cases of acute or chronic diarrheic disease, especia…

SCP SCIENCE ISO can prepare custom multi-element calibration standards to exact specifications. Indicate the desired elements and their concentrations, together with the desired matrix, and the company will recommend a mix stability for a minimum of 12 months (reduced shelf life for concentrations less than 1 ppm). A comprehensive Certificate of Analysis accompanies each standard.

Fluorescein sodium salt has been used as a solute to study microvessel permeability. It has been used as a test molecule to study blood barrier penetration. Water soluble fluorescent dye used in permeability and vascular perfusion studies due to its small molecular radius. Sodium fluorescein is used as a fluorescent tracer to study blood-brain barrier (BBB) and blood-spinal cord barrier (BSCB) permeability in rodent mode…

PBS (phosphate buffered saline) is a balanced salt solution used for a variety of cell culture applications, such as washing cells before dissociation, transporting cells or tissue, diluting cells for counting, and preparing reagents. PBS is formulated without calcium and magnesium for rinsing chelators from the culture before cell dissociation.
