TAE buffer is the most commonly used buffer for DNA agarose gel electrophoresis but is also used for non-denaturing RNA agarose gel electrophoresis1. Double-stranded DNA tends to run faster in TAE than in other buffers but can also become exhausted during extended electrophoresis.
Description
TAE buffer is the most commonly used buffer for DNA agarose gel electrophoresis but is also used for non-denaturing RNA agarose gel electrophoresis1. Double-stranded DNA tends to run faster in TAE than in other buffers but can also become exhausted during extended electrophoresis. Dilution of the concentrated TAE buffer produces a 1× TAE buffer with 40 mM Tris-acetate and 1 mM EDTA, pH 8.3. The 1× TAE buffer is used both in the agarose gel and as a running buffer.
Application
Casting and running buffer for agarose gel electrophoresis of nucleic acids.
Notes
0.4M Tris base, 0.4M acetate, 10mM EDTA, pH 8.0.
Recommended Storage Condition: Room temperature
Low concentration solutions of DNA are prone to DNA degradation or other loss. It is critical that optimal methods are employed for DNA suspension and long-term storage.
TE Buffer is a common molecular biology buffer used for protection of DNA and RNA from degradation. The Tris buffering agent and EDTA metal chelating properties help to protect DNA and RNA.
Acetylated BSA is used as a carrier protein and an enzyme stabilizer in which the absence of contaminants such as nucleases and proteases is vital. The acetylation process inactivates any trace of active nuclease activity. While the acetylation process does change BSA's binding characteristics and makes it inhibitory in PCR reactions, it is normally added to restriction digests.
CHAPS (3-[(3-cholamidopropyl)dimethylammonio]-1-propanesulfonate ) is a zwitterionic detergent used to solubilize proteins. It is used as a non-denaturing solvent in the process of protein purification and is especially useful in purifying membrane proteins.
Tris Buffered Saline (TBS) is an isotonic, non-toxic buffer used in some biomedical techniques to maintain pH within a relatively narrow range. TBS can shift pH relatively drastically as temperature changes, with the pKa declining approximately 0.03 units per degree Celsius rise in temperature.
TRITON X-114 is used in biochemical applications to solubilize and separate proteins due to its low cloud point (23 °C).
A routine use of agarose is ideal for daily analysis of nucleic acids by gel electrophoresis or blotting (Northern or Southern) and is also suitable for protein applications such as Ouchterlony and radial immunodiffusion (RID). It has low ethidium bromide and SYBR Green background staining.
Contains 100% active components and is a mixture of organic non - silicone polypropylene based polyether dispersions. Can be sterilized repeatedly.
MCLAB's RNA Storage Buffer, with optimized reagents and pH value, provides better preservation and greater RNA stability for valuable RNA samples than the standard EDTA and TE Buffer or just water.
EDTA, 0.5 M, pH 8.0, is a sterile-filtered solution of 0.5 M EDTA in H2O treated with diethyl pyrocarbonate (DEPC).
IPTG (isopropyl-beta-D-thiogalactopyranoside) is a highly stable synthetic analog of lactose. It inactivates the lac repressor and induces synthesis of beta-galactosidase, an enzyme that promotes lactose utilization. IPTG is used to induce expression of cloned genes under the control of the lac operon.
Ammonium acetate is a widely used reagent in molecular biology and chromatography. Suitable applications include the purification and precipitation of DNA and protein crystallization. Ammonium acetate is commonly used in HPLC and MS analysis of various compounds, such as oligosaccharides, proteins, and peptides.
TAE buffer is the most commonly used buffer for DNA agarose gel electrophoresis but is also used for non-denaturing RNA agarose gel electrophoresis1. Double-stranded DNA tends to run faster in TAE than in other buffers but can also become exhausted during extended electrophoresis.
