Quality Biological Inc TAE Buffer (50X), 10 Liters
TAE (Tris-Acetate EDTA Buffer) buffer provides faster electrophoretic migration of linear DNA and better resolution of supercoiled DNA. TAE Buffer may be more suitable than TBE, for electrophoresis if DNA is to be recovered from the agarose and purified using commercially available DNA purification kits.
Applications: TAE buffer has a relatively low buffering capacity, therefore, periodic replacement of the buffer during prolonged electrophoresis is recommended.
Storage Conditions: 15 °C to 30 °C
Shipping Condition: ambient temperature

Quality Biological Inc TE, pH 7.4, 100 mL
TE is composed of buffering agent Tris, and chelating agent EDTA. EDTA prevents degradation of DNA and RNA by chelating magnesium (or other divalent metal ions). Together, this Tris-EDTA based solution solubilizes DNA or RNA, while protecting it from degradation.
Applications: TE is useful for reconstituting nucleic acids, during DNA precipitation and other DNA applications, storing and diluting DNA and RNA, breaking protein-links in immuno-histochemistry procedures, and unmasking antigens and epitopes in formalin-fixed and paraffin-embedded tissue sections.
