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
Tris-Acetate-EDTA buffer (TAE)
TBE and TAE buffers are used for agarose and polyacrylamide gel electrophoresis.TBE buffer is suitable when analysing DNA fragments from PCR amplification, DNA isolation protocols, or DNA cloning experiments. It is adapted for separating smaller DNA fragments (less than 1500 bp on a 0.8% agarose gel).

Product description
In molecular biology, TBE and TAE buffers are used for agarose and polyacrylamide gel electrophoresis.TBE buffer is suitable when analysing DNA fragments from PCR amplification, DNA isolation protocols, or DNA cloning experiments. It is adapted for separating smaller DNA fragments (less than 1500 bp on a 0.8% agarose gel).
TAE is advantageous for high resolution of long nucleic acid fragments (longer than 1500 bp) on agarose gels. It has a lower buffering capacity than TBE and in general, nucleic acid fragments move slower in TAE gels (apart from linear dsDNA, which tends to run faster). TBE has a greater buffering capacity and will give sharper resolution than TAE. However, TBE gels in general afford a poor recovery of nucleic acids compared with TAE gels. TAE is also used for native (non-denaturing) RNA analysis and in denaturing gels (instead of MOPS buffer) using prior denaturation of the RNA samples in hot formamide.
Medicago’s TBE and TAE buffers are supplied as a pre-weighed powder mix in sealed pouches giving 1000 ml of 1x, 5x or 10x Tris-borate-EDTA buffer or 50x Tris-acetate-EDTA buffer with pH 8.3 at 25°C.
