The most popular amine-reactive biotinylation reagent for antibody labeling Thermo Scientific™ EZ-Link™ Sulfo-NHS-LC-Biotin and Labeling Kits Features: Water-soluble analog of NHS-LC-Biotin Reacts with primary amines at pH 7-9 in non-amine-containing buffers such as borate, carbonate or phosphate buffers Negative charge of -SO3 group keeps biotinylation localized at the cell surface Creates an amide bond Applicatio…

The PCT Pre-Crystallization Test is used to determine the appropriate protein concentration for crystallization screening. Sample concentration is a significant crystallization variable. Samples too concentrated can result in amorphous precipitate, while samples too dilute can result in clear drops. Precipitate and clear drops are typical crystallization screen results for reagent conditions which do not promote crystallizati…

Axygen® Universal Tips are designed to fit a wide variety of single and multi-channel pipettors. These polypropylene tips are certified to be RNase-/DNase-free and nonpyrogenic. They are available in Maxymum Recovery, bevelled, Eppendorf-style, nonsterile, sterile, non-filtered, and other features for specialized applications. Flexible walls and a series of internal sealing rings ensure a secure fit with less force required t…

OneTaq DNA Polymerase is an optimized blend of Taq and Deep VentR™ DNA polymerases for use with routine and difficult PCR experiments. The 3´→ 5´ exonuclease activity of Deep Vent DNA Polymerase increases the fidelity and robust amplification of Taq DNA Polymerase. The OneTaq Reaction Buffers and High GC Enhancer have been formulated for robust yields with minimal optimization, regardless of a template’s GC content.OneTaq DNA…

Q5® High-Fidelity DNA Polymerase is a high-fidelity, thermostable DNA polymerase with 3´→ 5´ exonuclease activity, fused to a processivity-enhancing Sso7d domain to support robust DNA amplification. With an error rate > 100-fold lower than that of Taq DNA Polymerase and 12-fold lower than that of Pyrococcus furiosus (Pfu) DNA Polymerase, Q5 High-Fidelity DNA Polymerase is ideal for cloning and can be used for long or difficul…

The EasyCell® assistant is a state-of-the-art hematology system that uses image-processing and pattern-recognition technologies to automate white cell differentials. EasyCell automatically locates white cells on a blood smear, preclassifies the cells, and then presents them to a technologist for review on an LCD display. The hematology system typically reduces sample review times by 50% over the manual differentiation method…

External thread screw top tubes provide greater working volume, and require less freezer space, than internal thread alternatives. 3 different volumes: 0.3 ml, 0.7 ml, 1.0 ml External Thread Screw Cap 2D Storage Jacket Tubes Features: Space saving. Thread on the outside of the tube helps maximize the internal volume to the total height of the tube. Excellent seal performance. No silicone seal is used, the cap cannot be…

The Agilent 7900 ICP-MS is a flexible single quadrupole ICP mass spectrometer that provides the industry’s best matrix tolerance, most effective helium collision mode, lowest detection limits, and widest dynamic range. As a result, you can be confident you are reporting accurate data every time, even at trace levels, whatever your sample types.
