Qdot 655 Antibody Conjugation Kit enables users to conjugate antibodies of interest to Qdot 655 Nanocrystals.
Microfluidics-based technology for liquid chromatography/mass spectrometry (LC/MS) (Agilent Technologies, Inc.), is built upon a reusable polymer HPLC chip that replaces LC columns.
New 12 channel Ovation BioNatural pipettes share the ergonomic design features as single channel models, and include a number of new electronic programmable functions to further minimize physical effort and save time. Four 12-channel models provide dispensing from 0.5μl to 850 μl.
Sony Visual Imaging Products has introduced six IEEE 1394 high-resolution digital cameras that are available for bioscience applications.
Type 3 Micro-Fluorimeter Cells not only permit stirring, but with FCA adaptors, they can also be used in a standard 12.5-mm square fluorimeter cell holder.
The antioxidant system of living organisms includes enzymes such as superoxide, dismutase,
Vortex autosampler consists of an integrated autosampling device and multi-stirrer, and increases efficiency, enhances precision, and promotes operator safety. The temperature-controlled, heated (up to 150 C) multi-stirrer assembly features a stainless steel tray that handles 20- and 40-ml vials.
Microwave Fixation System preserves levels of enzyme-regulated neurotransmitters and metabolic substances in the brain at concentrations that exist in the living tissue, while brain size and structure remain unchanged.
Having applications in colorectal cancer, the p21 waf-1 protein is a p53-regulated gene product that mediates cell cycle arrest. Levels of p21 are reduced or negligible in tumor cells that are lacking the p53 protein or contain a mutant form of p53.
Equipped with sensitive microprocessor-based PID controllers, these stationary and shaking water baths maintain temperatures from ambient +5 to 100 C with ۯ C accuracy and ۪.2 C uniformity.
Glass bottle line consists of versatile, multi-use sampling and storage containers each made of Type III soda lime. Valumetric bottles are graduated in milliliters and ounces, for use as sample bottles or for dry powders, soil samples, and for specimen storage.
Cheminert C2XH series injectors are rated for use at up to 10,000 psi liquid and employ the patented feedback system used in the Extended Life Injectors (C2XL series). Injectors feature proprietary 1/16 fittings and are available with 0.010 or 0.016 bore (0.25 or 0.
TCS 4Pi fluorescence microscope system uses a phase- and wavefront-corrected double objective imaging system linked to a confocal scanner to enable a four- to seven-fold increased axial resolution over confocal and two-photon microscopy.
POLYTRON PT 1200 E handheld ergonomic homogenizer minimizes the stresses of routine and repetitive homogenization in the laboratory. With a 100-W motor and fingertip speed control up to 25,000 rpm, the 1200 E processes samples up to 250 ml.
