Lab Reagents: Smart Buffers and ReagentsBiological 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 reproducibilityCatalogueDescriptionReferencesApplications & BenefitsPhosphate Buffered Saline (PBS) pH 7.2 & 7.4Among biological buffers PBS is one of the most commonly used.

The buffer is isotonic and non-toxic to cells and has the ability to maintain their osmolarity. Thereby the buffer is suitable for washing procedures in cell cultures and for immunoassays such as ELISA and immuno-histochemical procedures. It is often used for sample dilution in molecular biology and as protein diluent in Western blotting. Furthermore, the buffer can function as an equilibrator for gel filter columns (1).Medicago’s PBS is specifically developed for immunological and microbiological laboratories. It is provided as pre-weighed tablets in containers and in convenient blister packs, or as pre-weighed powder mix in sealed pouches. There are seventeen standard-sized packages and final volumes range from 100 ml to 100 litres. Choose from different pH, 7.2 and 7.4 and from PBS with or without potassium. PBS without potassium is available in two different molar strengths, 0.01 M and 0.02 M. PBS solution is supplied as a ready-to-use solution.Directions for useEmpty one pouch or deposit one tablet in a laboratory flask or beaker placed on a magnetic stirrer. Add 50 ml to 500 ml of deionized water for pouches and tablets in the volume range 100 ml to 1000 ml and stir the solution for a few minutes. Adjust the water up to the given volume, stir until full dissolution and the buffer is ready to use. For larger quantities, 10 to 100 litresof buffer, use suitable equipment to stir and dissolve the buffer in compliance with the instructions above.Shipping and storagePBS buffer is shipped at room temperature. Store the tablets and pouches in a dry place at room temperature. Shelf life is three years after production date..
