Buffers and Standards
Hydrogen ion buffers comprising a mixture of a weak acid and its conjugate base or vice-versa and used to stabilize pH; also diluents, washing solutions, and standard-value solutions used for a broad array of scientific calibration purposes.
The buffers used to calibrate pH meters may be certified and/or traceable to the National Institute of Standards and Technology (NIST). These buffers may also be color-coded for easy identification:
- Red: pH 4.0
- Yellow: pH 7.0
- Blue: pH 10.0
Invitrogen™ NuPAGE™ MOPS SDS Running Buffer (20X)
Made with high-purity reagents and are strictly quality controlled.
Invitrogen™ Novex™ Tris-Glycine SDS Running Buffer (10X)
Formulated for separation of proteins, in their denatured state, on Novex Tris-Glycine gels
Thermo Scientific Chemicals TBE running buffer (10X)
Commonly used in nucleic acid electrophoresis. TBE Buffer is used for polyacrylamide and agarose gel electrophoresis. It is ideally suited for DNA and RNA separation on longer run, higher voltage or amperage gels. TBE is used with non-denaturing or denaturing (7 M urea) gels.
Thermo Scientific Chemicals TRIS-glycine-SDS running buffer (10X), pH 8.5
TRIS-glycine-SDS running buffer (10X), suitable for protein gel analysis, is used in several research areas, including biochemistry, molecular biology, cell biology, and immunology.
Invitrogen™ 20X Bolt™ MOPS SDS Running Buffer
Optimized for use with Bolt™ Bis-Tris Plus gels, and are available in a variety of formats
Thermo Scientific Chemicals MOPS-SDS running buffer (20X)
MOPS-SDS running buffer (20X) is a buffer frequently used for separating medium- to large-sized proteins on a gel.
Invitrogen™ NuPAGE™ MES SDS Running Buffer (20X)
Made with high-purity reagents and are strictly quality controlled
Invitrogen™ 20X Bolt™ MES SDS Running Buffer
Optimized for use with Bolt™ Bis-Tris Plus gels, and are available in a variety of formats
Invitrogen™ Novex™ Tricine SDS Running Buffer (10X)
Novex Tricine SDS Running Buffer (10X) is formulated for separation of proteins in their denatured state on tricine gels.
