Electrophoresis Buffers
QuickSilver - TAE (Tris-acetate-EDTA)

TAE is ideal for separation of large DNA fragments in agarose gels and is used as running buffer and in gel preparation.

TAE is the buffer of choice when recovering DNA from gels and when downstream processing involves enzymatic reactions. Final concentration of a 1X working solution is 40mM Tris, 20mM acetic acid, 1mM EDTA.

QuickSilver - TBE (Tris-borate-EDTA)

TBE is used in gel preparation and as a running buffer for electrophoresis of nucleic acids. TBE works best for resolution of smaller fragments (<2kb). Its higher buffering capacity makes it useful for longer runs. The final concentration of a 1X working solution is 89mM Tris, 89mM boric acid, 2mM EDTA.

QuickSilver - Fast Running Buffer

QuickSilver Fast Running Buffer is a proprietary blend formulated for agarose gel electrophoresis at high voltage (300-350V). Its strong buffering capacity minimizes heat generation all allows for extremely fast separation of fragments smaller than 5kb. A typical 30-minute run can be performed in just 10 minutes using this buffer.

QuickSilver™ Tris-MES-SDS

Small to medium molecular weight proteins can be resolved on SDS-PAGE gels using Tris-MES-SDS as a running buffer. Proteins resolve faster in gels using Tris-MES-SDS as a running buffer than those using Tris-MOPS-SDS. A 1X solution has a final concentration of 50mM Tris, 50mM MES, 0.1% SDS and 1mM EDTA.

QS1101 QuickSilver Tris-MES-SDS Buffer, 1X, 50 packs


QuickSilver™ Tris-MOPS-SDS

Tris-MOPS-SDS is ideal for use as a running buffer when resolving medium to large proteins with SDS-PAGE. Gels run with Tris-MOPS-SDS buffer run slower than those using Tris-MES-SDS buffer. The final concentration of a 1X working solution is 50mM Tris, 50mM MOPS, 0.1% SDS and 1mM EDTA.

ION Biosciences Fluo-2 K+ Salt

Green fluorescent, calcium (Ca²+) indicator, membrane impermeable. Higher Ca²+ affinity than Fluo-4.

Fluo-2 is a green fluorescent, calcium (Ca²+) indicator. Fluo-2 has higher Ca²+ affinity (Kd = 290 nM), superior cell loading and comparable spectral properties compared to Fluo-4. Offers superior sensitivity versus other Fluo analogues at lower Ca²+ concentrations.

Fluo-2 K+ salt is a membrane impermeable form of Fluo-2 that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.

ION Biosciences Fura-2 LR K+ Salt
 
Leakage-resistant, ratiometric calcium (Ca²+) indicator, membrane impermeable.
 
UV-excitable, ratiometric green indicator for intracellular calcium (Ca²+) measurements with longer cellular retention compared to Fura-2 AM and similar spectral properties. Ex/Em: 340/505 nm can be used to measure Ca²+-bound Fura-2, and Ex/Em: 380/505 nm can be used to detect Ca²+-free Fura-2. Ratiometry is optimal for imaging applications where quantification of intracellular Ca²+ concentrations is desired, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology.
 
Fura-2 LR K+ salt is a membrane impermeable form of Fura-2 LR that can be used in lipid membrane-free systems, in liposomes, or can be introduced into cells by electroporation, microinjection or other methods.
ION Biosciences BCECF AM

BCECF AM is the most popular green fluorescent, intracellular pH indicator. BCECF has a pKa of ~7, and exhibits pH-dependent, dual-excitation properties (Ex/Em 430nm/535nm and 490nm/535nm) for ratiometric analysis. Ratiometry is optimal for imaging applications, and reduces effects of photobleaching, heterogenous dye loading, and variable cell morphology. For HTS applications, BCECF can also be used in non-ratiometric mode using standard fluorescein excitation and emission settings.
ION Biosciences Brilliant Sodium Flex Kit
 
ION’s Brilliant Sodium Assay is a total assay solution for multi-well plate-based, high-throughput measurements of changes in intracellular Na+ mediated through a wide-variety of plasma membrane and intracellular sodium channels and transporters. In multi-well, plate-based formats, the Brilliant Sodium Assay can be used to discover and characterize the effects of many tens-of-thousands of compounds and environmental factors on effectors of intracellular Na+. ION’s Brilliant Sodium Assay provides all the reagents necessary for use as a wash or no-wash assay with adherent or non-adherent cells. The optional use of a probenecid solution and an extracellular background masking solution (TRS) offers the ultimate in compatibility for cells types which are difficult to load with fluorescent Na+ indicators (e.g. Chinese Hamster Ovary, CHO cells) and when performing assays in complete, serum-containing cell culture medium is desired.
 
ION’s Brilliant Sodium Assay is compatible with fluorescence microscopes, flow cytometers, and plate readers capable of detecting fluorescein or more optimally, yellow fluorescent protein (YFP).
