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
Medchemexpress LLC Nvp-tae 226 | 761437-28-9 | MFCD12031516 | 99.8% | 468.94 g·mol⁻¹ | C23H25ClN6O3 | 5 MG
NVP-TAE 226 is an ATP-competitive small-molecule inhibitor of focal adhesion kinase (FAK) and insulin-like growth factor 1 receptor (IGF-1R), used in cellular and preclinical cancer research to probe signaling pathways and evaluate effects on proliferation, migration, and survival.
- Potent inhibition of FAK and Pyk2 with low-nanomolar IC50s.
- Also inhibits IGF-1R and insulin receptor, enabling study of connected signaling networks.
- Suitable for in vitro assays and preclinical efficacy models.
- Available as solid and solution formulations for flexible dosing.
- High purity appropriate for research applications.
- Stable under recommended storage conditions for prolonged shelf life.
Epigentek Inc TET ASSAY BUFFER (6ML)
The TET Assay Buffer is a component of Epigenase 5mC Hydroxylase TETActivity/Inhibition Assay Kit (Colorimetric)
Quality Biological Inc TAE Buffer 50X, CS 10 X 1000 mL
TAE 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 ¿ Sterile Filtered ¿ DNase RNase and Protease Tested ¿ Concentration: 2 M Tris base and 0.05 M disodium EDTA dihydrate ¿ Product and/or packaging contains recycled/renewable content ¿ Product and/or packaging is recyclable or reduces waste ¿ Product and/or packaging is safer to human and environmental health ¿ ¿ Max Shelf Life: 36 months
