Heparin Sepharose 6 Fast Flow is composed of cross-linked 6% agarose beads modified sodium heparin. Immobilization is performed using chemically stable and oriented coupling giving high binding capacity. The chemical stability of the media is solely dictated by the heparin ligand. Heparin Sepharose 6 Fast Flow is a member of the Cytiva range of affinity chromatography media for capture and intermediate purification.

Thermo Scientific Pierce EDC is a carboxyl- and amine-reactive zero-length crosslinker. EDC reacts with a carboxyl group first and forms an amine-reactive O-acylisourea intermediate that quickly reacts with an amino group to form an amide bond with release of an isourea by-product. The intermediate is unstable in aqueous solutions and so two-step conjugation procedures rely on N-hydroxysuccinimide (NHS) for stabilization. Failure to react with an amine will result in hydrolysis of the intermediate, regeneration of the carboxyl, and release of an N-substituted urea. A side reaction is the formation of an N-acylurea, which is usually restricted to carboxyls located in hydrophobic regions of proteins.

The key to outstanding, reproducible electrophoresis results is temperature control. Gels unequally cooled on their two faces produce slanted bands appearing as broad or double bands in stained gels. SE 600 Ruby™ ensures uniform heat in gels because, firstly, the gels are completely immersed in the lower buffer for uniform heat transfer and, secondly, a standard magnetic stirrer circulates buffer around the vertically suspended heat exchanger to maintain homogeneous lower buffer temperature. The ergonomically designed SE 600 Ruby™ provides two built-in side handles, which facilitates carrying and handling.

Successful PCR applications depend on well purified DNA. In diagnostics and analytics of food and medical samples PCR and real-time PCR has many advantages over conventional methods. In all cases it is of importance to have well purified DNA for subsequent PCR, real-time PCR, hybridization or sequencing purposes. Purified DNA leads to higher sensitivity and also specificity of PCR based tests in difficult matrices. With QuickBlue Extraction and Purification Kit you always get high DNA yields and highly purified DNA. The kit uses paramagnetic nano-particles for purification. It can help to purify DNA from difficult matrices like food or even blood in soil for applications in forensic sciences. DNA in Seawater can also be purified. This method avoids extensive centrifugation steps and can thus be applied in environments where centrifuges are not usable. The kits includes proteinase K as a reagent for cell disruption, so that extraction and purification can be performed with the kit. DNA yield from 1 ml bacterial enrichment is 10 μg of Genomic DNA. The protocol can be adapted to automated magnetic bead separation instruments.
