Lab Reagents: Smart Buffers and Reagents
Biological buffers for the life science laboratory need to meet a wide array of criteria. These include good stability, lack of toxicity, precision in pH, pKa between 6.0 and 8.0 (the region in which most biological reactions occur), minimal salt effects due to the ionic composition of the solution, free of enzymatic and hydrolytic activity and minimal participation in biological reactions.
Buffers for molecular biology applications, e.g. Tris-Borate-EDTA and Tris-Acetate-EDTA, need to be free from DNAse and RNAse activity. Medicago's SmartBuffers meet all these criteria. They are manufactured using highly purified, analytical grade chemicals and are extensively quality tested. Manufacturing is done in a controlled clean environment according to GMP procedures.
A high level of automation essentially avoids operator intervention and contact with the products.
SmartBuffers are supplied as exactly pre-weighed tablets packed in containers or blister packs or as exactly pre-weighed powder mixes packed in sealed aluminium foil pouches.
•Pre-mixed powder buffers or tablets with pre-set pH
•Analytical grade reagents
•Eliminates calculation, formulation and weighing errors
•Dissolve-and-go for greater convenience
•Stable at room temperature for at least 3 years
•Guaranteed reproducibility
Saponin from Gypsophila oldhamiana
Saponins are amphiphilic glycosides widely distributed in nature. Saponins from the Gypsophila species have long been known to exhibit hemolytic activity in very low concentrations. This product is a mixture of the saponins with the highest hemolytic activity from the roots of Gypsophila oldhamiana.

Product description
Saponins are amphiphilic glycosides widely distributed in nature. Saponins from the Gypsophila species
have long been known to exhibit hemolytic activity in very low
concentrations. This product is a mixture of the saponins with the
highest hemolytic activity from the roots of Gypsophila oldhamiana.
Some saponins from Gypsophila oldhamiana have been shown to have pancreatic lipase-inhibiting (Zheng et al.), α-glucosidase-inhibiting as well as adjuvant activities (Kong et al.).
