Life Science Buffers
Teknova 20x PBS with 0.05% Tween-20. 500mL, Sterile. 8 pack.
Phosphate-buffered saline (PBS) is a salt solution that is commonly used in physiological and biochemical experiments. It can be used to maintain pH neutrality or to buffer against changes in pH in order to provide optimal conditions for cellular growth and function. The buffering range is between pH 6.8 and 7.4.
Cambridge Isotope Laboratories CDC BFR PAR Solution (unlabeled) 1000 ng/mL in nonane 1 2 mL
CDC BFR PAR Solution (unlabeled) 1000 ng/mL in nonane 1 2 mL
Teknova TE Buffer with 0.1 mM EDTA, pH 7.6, RNAse/DNAse Tested, 500mL, Sterile. 4 pack.
TE buffer is a salt solution that is commonly used to resuspend (or dilute) DNA and RNA. Composed of Tris base and EDTA, these molecules work together to maintain pH and prevent nucleic acids from degradation.

Reliable and Economical, 18 Megohm Water, and 0.2 Micron Filtered. Ideal running buffer for high resolution SDS PAGE of proteins. 20X concentrate makes a working solution of 50mM Tris MOPS, 0.1% SDS and 1mM EDTA.
Alkali Scientific CellPro™ 1X Balanced Salt Solution, 500ml
Balanced salt solution for cell culture applications. All formulations incorporate a rigorous specification and approval process. Available in lot sizes that facilitate scale-up and manufacturing.
Bioworld STEBuffer (1X), 4 L
STE Reagent Common reagent for molecular biology. Used in DNA extraction, DNA electrophoresis and many other lab protocols.DNAse and RNAse free, ready to use 1X solution Technical Information:NaCl (100mM) Tris-HCl, pH 8.0 (10mM) EDTA, pH 8.0 (1mM)
Bioworld TBE Buffer (25X), 4 L
Product DescriptionTBE (Tris-Borate-EDTA) has a liquid concentrate of 25X, where 1X contains 0.089M Tris, 0.089M Borate, and 0.002M EDTA. 1L of concentrate makes 25L of 1X buffer. Tris solutions are effective buffers for slightly basic conditions. Borate, a derivative of boric acid, is a weak proton donor but a Lewis acid that can accept an electron pair. EDTA is a chelator of divalent cations, mainly Mg2+. TBE is most commonly used for nucleic acid electrophoresis.For laboratory use only. Not fit for agricultural, household, clinical use or human consumption.
Bioworld TBE Buffer, Quick-Mix Pack (25X), 2 PK(s)
Product DescriptionTBE (Tris-Borate-EDTA) quick-mix pack prepares 1L of 25X concentrate. Each pack contains 0.089M Tris, 0.089M Borate, and 0.002M EDTA. Tris solutions are effective buffers for slightly basic conditions. Borate, a derivative of boric acid, is a weak proton donor but a Lewis acid that can accept an electron pair. EDTA is a chelator of divalent cations, mainly Mg2+. TBE is most commonly used for nucleic acid electrophoresis.For laboratory use only. Not fit for agricultural, household, clinical use or human consumption.
Bioworld TAE Buffer (10X), 1 L
Product DescriptionTAE (Tris-Acetate-EDTA) buffer liquid concentrate has a 10X concentration and is prepared with 18 megohm water. It has a pH of 8.3 ± 0.2. A concentration of 1X contains 0.4M Tris acetate and 0.01M EDTA. TAE is used for electrophoresis of nucleic acids in agarose and polyacrylamide gels. It can be used for both genomic and large supercoiled DNA, and can also be used as both a running buffer and a gel preparation buffer. It is recommended for resolution of RNA and DNA fragments larger than 1500 bp, for genomic DNA and for large supercoiled DNA. TAE buffer has a relatively low buffering capacity and therefore replacement of the buffer during prolonged electrophoresis is recommended.
Bioworld TBE Sample Buffer (6X), 50 mL
Product DescriptionTBE (Tris-Borate-EDTA) is a sample buffer used for nucleic acid analysis. It has a 6X concentration, 270 mM Tris base, 270 mM boric acid, 40% glycerol, 0.025% bromophenol blue G, 0.025% xylene cyanol, and 6 mM of EDTA.For laboratory use only. Not fit for agricultural, household, clinical use or human consumption.
