TE buffer, pH 7.4, RNAse free

TE buffer is a commonly used buffer solution in procedures involving DNA or RNA. It is used for storing and diluting DNA and RNA. Treatment with TE buffer enhances the staining intensity of antibodies in the immunohistochemical detection of certain proteins.

Potassium phosphate, 0.2M buffer soln., pH 7.5

Potassium phosphate buffer is typically used as a component for a wide variety of media used in the culture of microorganisms, as a component in phosphate buffered saline (PBS). In addition to helping maintain pH, it supplies essential phosphate.

TRIS, 0.5M buffer soln., pH 7.5

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo...

MES, 0.2M buffer soln., pH 6.0

MES is used as a running buffer for resolving very small proteins (ex: 13 kDa) on bis-tris gels. Also used in cation-exchange chromatography and as a biological buffer in plant cell cultures. Used in various protein characterization assays.

Phosphate-buffered saline (PBS, 5X), with EDTA

PBS with EDTA is also used to disengage attached and clumped cells. PBS-EDTA is used as a buffer in procedures generating dendritic cells from monocytes. PBS+EDTA to get better cell sorting. PBS/EDTA may also be used directly without addition of trypsine for very gentle cell dissociation.

TRIS, 0.5M buffer soln., pH 8.8

HEPES, 1.0M buffer soln., pH 7.5

HEPES is common buffer for biological sciences, particularly used in cell culture to maintain physiological pH. It acts a buffering component, which is used in the preparation of buffers. It is described as one of the best all-purpose buffers available for use in biological research.

TBE (5X), TRIS + borate + EDTA

Imidazole, 0.5M buffer soln., pH 7.5

Imidazole is used as a chelator for the binding of various divalent cations, and is also used to elute tagged proteins bound to Ni ions attached to the surface of beads in the chromatography column. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product...

TRIS, 1.0M 缓冲液, pH 7.4

Tris is used in pH control in buffering systems for electrophoresis applications.Tris is used in assays used to characterize the activity and kinetics of the enzymes that catalyze SUMOylation of Small ubiquitin-like proteins (SUMO) and SUMO-dependent protein-protein interactions.

CHES, 0.5M buffer soln, pH 9.0

Phosphate-buffered saline (PBS, 10X), with Triton∣r X-100

Phosphate-buffered saline is used in biological research. PBS buffer is ideal for maintaining a constant pH, and since it is isotonic to cells. PBS is frequently used as a wash and dilution buffer, and is also used to take a reference spectrum when measuring protein adsorption.

TRIS, 0.5M buffer soln., pH 6.8

TRIS is used as a standard biological buffer in less critical applications where economy is an important consideration, component of extraction buffer e.g. phenol extraction of DNA or RNA; and as a component of separating and stacking gels in the characterization of in vitro translation products by...

HEPES, 0.5M buffer soln., pH 8.0

HEPES has been utilized extensively for research and commercial applications in the cell culture and tissue culture industries. It is useful in the pH range 6.8-8.2. HEPES is used as a zwitterionic, all-purpose Good’s buffer for use in biological research.

MES, 0.2M buffer soln., pH 5.5

MES is used as a running buffer for resolving very small proteins on bis-tris gels, also used as a biological buffer in plant cell cultures. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio.
