Life Science Buffers
Balanced salt solutions and powders used for molecular, protein, nucleic acid, and cell biology applications including cell culture, electrophoresis, ELISA, and chromatography processes; available in a variety of formulations and grades.
Buffer solutions serve to keep pH (acidity or alkalinity) nearly constant in a variety of chemical and biological applications. For example, a bicarbonate buffer helps maintain the pH of blood, a buffered saline maintains cellular contents at a consistent pH level, and buffers help maintain a narrow pH range for enzymes to function correctly.
Most biological samples used in research are kept at a pH of about 7.4. Common biological buffers used for tissue culture include Dulbeccos phosphate buffered saline (PBS), Tris base, HEPES, MOPS, PIPES, and other formulations developed for specific cell lines or applications. Most buffers used in cell culture are also DNase-, RNase-, and protease-free.
The choice of buffer for a particular biological reaction or site depends on several factors:
- Temperature
- Desired or target pH
- Buffer toxicity (to the system)
- Buffer interactions with other system components

NVP-TAE 226 is a potent, ATP-competitive small-molecule inhibitor of focal adhesion kinase (FAK) and insulin-like growth factor 1 receptor (IGF-1R), used in preclinical oncology and signal-transduction research. It exhibits activity across multiple kinases and has demonstrated antitumor effects in vitro and in vivo.
- Potent FAK inhibition (IC50 5.5 nM).
- Dual activity against IGF-1R and Pyk2 (IC50 140 nM and 3.5 nM).
- Additional activity against InsR, c-Met, KDR, and Flt3.
- High purity suitable for research (~99.8%).
- Stable as powder under recommended storage conditions.
LICOR Odyssey MES SDS Running Buffer Powder (pack of 5)
Odyssey Mini Gels are polyacrylamide gels designed to separate a wide range of protein sizes via PAGE or SDS-PAGE. Each box contains 10 pre-cast gels. Our gels feature larger well volumes for easier sample loading and are cast in a neutral pH buffer to increase gel stability. They also run at neutral pH, which minimizes protein modification compared to Tris-glycine gels. Odyssey Mini Gels are available in several gradients with 10, 12, or 15 numbered wells. Our gels feature a shelf life of up to 6 months at room temperature and 12 months at 2–8C.
