TMB substrate is a chromogenic substrate for horseradish peroxidase - HRP.
Sigma Aldrich Fine Chemicals Biosciences HiLoadR 16/600 SuperdexR 2
HiLoad(R) 16/600 Superdex(R) 200 prep grade are prepacked XK columns designed for high-resolution preparative gel filtration chromatography. The column is an excellent choice for separating MAbs from dimers and contaminants.Superdex(R) prep grade (pg) is produced by covalent bonding of dextran to highly cross-linked agarose.The separation properties of these media are determined by the dextran component. Steep selectivity curves give excellent resolving power for peptides and proteins in the molecular weight ranges Mr < 10 000 (Superdex(R) 30 pg) Mr 3 000 to 70 000 (Superdex(R) 75 pg) and Mr 10 000 600 000 (Superdex(R) 200 pg). The medium combines high mechanical strength with high hydrophilicity allowing high flow rates and minimal nonspecific interactions.
Sigma Aldrich Fine Chemicals Biosciences DuranR double walled jacke1EA
The DURAN double walled wide mouth bottles GLSA80 incorporate an integral jacket that isolates the contents from the external environment. Heated or cooled liquids can be circulated through the jacket to control the temperature within the screw topped DURAN bottle. The DURAN double walled bottles offer a sealable and more flexible alternative to open topped jacketed beakers.
Sigma Aldrich Fine Chemicals Biosciences BenchRockerTM variable 2D1EA
The BenchRocker 2D is designed to provide the precise speeds and tilt angles required for a broad range of molecular and biological mixing applications. The user can adjust both parameters to match the vessel size and the volume of liquid being mixed yielding optimum results.
Sigma Aldrich Fine Chemicals Biosciences PyrexR large top desiccato1EA
These 10.5L PYREX desiccators have rugged 24/29 Standard Taper external sleeves with tooled hose connections that serves as the stopcock. They are designed so that its manipulation is not affected by the vacuum. The open position is indicated by the molded arrow on the cap. A quarter turn from this position closes the desiccator. For ease in use and improved performance it is recommended that the Standard Taper sleeve be lubricated with a silicone-based vacuum grease. The tubulation O.D. is approximately 10mm. Bowl capacity is 10 500mL. Warning Do not heat or subject to pressure. Rated 1- atmosphere vacuum.

Sigma Aldrich Fine Chemicals Biosciences DuolinkR In Situ Detection
Duolink(R) In Situ Detection Reagents Green contains all the necessary Duolink In situ reagents to perform the amplification and detection of bound PLA(R) probes. The detection probes contain a fluorophore (lex 495 nm and lem 527 nm) which may be visualized using the same filter as Cy(R)2 or fITC. Experiments conducted using Duolink In situ reagents can detect and visualize protein interactions protein expression levels and post translational modifications at the single molecule level in fixed cells and tissue samples.
Alkali Scientific High Sensitivity dsDNA Quantif
Alkali Scientific DNA Quantification Kits Alkali Scientific DNA Quantification Kits are designed for accurate fluorescent quantification of dsDNA using an instrument such as the SmartDrop XF Qubitor Alkali ScientificFluorometer The reagents are highly selective for double-stranded DNA (dsDNA) and not for single-stranded DNA (ssDNA) RNA protein or nucleotides Included with each kit are a concentrated assay reagent dilution buffer and ready-to-use DNA standards The assay reagent is diluted using the buffer provided sample is added (1 L to 20 L of sample is needed) and the concentration can be determined using an appropriate fluorometer instrument High Sensitivity dsDNA Assay KitThe Alkali Scientific High Sensitivity kitprovides an accurate method for quantitation of dsDNA samples when sensitivity is required Depending on sample volume the assay kit is designed to be accurate for initial DNA sample concentrations of 0 005 to 120 ng/ L providing a detection range of 0 1120 ng
