Automated Liquid Dispenser

The new Fill-It 48-way system has been developed to meet scientists' need to dispense up to 5 ml in an aseptic environment into Nunc's preloaded 48-way racks of 2D barcoded 2- and 5-ml vials. The benefit of automatically filling larger volumes of potentially hazardous biological materials is that researchers can increase their production of cell line libraries and cell banks without compromising sample integrity or their safety. The new Fill-It 48-way system is compact enough to fit in a standard laboratory tissue culture cabinet or its own specially designed mobile class II biological safety cabinet. Fill-It's safety cabinet can be automatically moved up and down to suit each researcher's height. The system and cabinet can be easily sterilized using hydrogen peroxide, thus providing a safer alternative to formaldehyde decontamination.

Non-Interfering Protein Assay

The Non-Interfering (NI) Protein Assay is a highly sensitive colorimetric protein assay that overcomes interference of common laboratory agents present in protein solutions. The NI Protein Assay has a small sample requirement of only 1 μl to 50 μl and a linear response of 0.5 μg to 50 μg protein. It is also fast, easy to use, and unaffected by the presence of common laboratory agents such as reducing agents, chelating agents, detergents, chaotropes, salts, and other agents making it ideal for all your research needs. The product is suitable for the estimation of protein during protein purification, electrophoresis, cell biology, molecular biology, and other research applications. Kits are sufficient for 500 assays.

Normal Human Primary Corneal Epithelial Cells

Normal human primary corneal epithelial cells are a perfect alternative test method platform for toxicological assays, and can also be used in research related to gene regulation, tissue development, wound healing, cell-matrix interactions, and drug development. ATCC Normal Human Primary Corneal Epithelial Cells have undergone sterility testing for bacteria, yeast, fungi, and Mycoplasma as well as viral testing for HIV and HCV. The cells are cryopreserved in the second passage to ensure the greatest purity coupled with high viability and plating efficiency. As part of ATCC Primary Cell Solutions, each lot of cells is performance tested with a matched set of components including media, growth factors, and reagents. Corneal Epithelial Cell Basal Media contains essential and nonessential amino acids, vitamins, other organic compounds, trace minerals, and inorganic salts in a formula designed to support proliferation of cells originating from a human cornea.

Graphene Support Films

New graphene transmission electron microscopy (TEM) support films provide an invisible, crystalline background that enables the unrivaled TEM characterization of organic and inorganic nanomaterials. Graphene is electrically and thermally conductive, and is the strongest material ever measured. These remarkable properties make graphene the ideal support film for electron microscopy. The graphene used in the support films is produced by the substrate-free, gas-phase method, which is the first and only process that can synthesize ultrahigh-quality graphene in a single step without the use of substrates or graphite. This technique results in graphene with a highly ordered structure that is composed of 99 percent carbon by mass (1% hydrogen) and can be used to directly image gold nanoparticles and their organic surface molecules in both conventional and atomic-resolution TEMs at a level that greatly surpasses any current TEM support film.

Animal-free Human Serum Albumin

ecoHSA provides an animal-free preparation of the human albumin gene produced in the seeds of Asian Rice (Oryza sativa). ecoHSA offers significant advantages over traditional albumins by eliminating the risk of animal or viral infectious agents in cell cultures and helping researchers comply with FDA recommendations for animal-free components. Extensively tested in multiple functional studies, ecoHSA has been proven to be similar in structure and biochemical function to native HSA in all tests performed. Furthermore, rigorous standards and procedures in the manufacturing process of ecoHSA ensure minimal batch-to-batch variability. In tests ecoHSA has been shown to improve the health of cells by acting as a fatty acid carrier and hydrophobic moiety scavenger. In addition, ecoHSA extends the life of cell cultures by scavenging toxins as well as stabilizing membrane proteins and maintaining oncotic pressure thereby providing better cultures and results.

Solid Phase Extraction microplate

The Development Microlute solid phase extraction (SPE) microplates provide a wide assortment of phase chemistries and sorbent loadings in a single plate making it ideal for method development. The mix of phase chemistries and sorbent loadings available in the Development Microlute allows you to simply and rapidly screen for the optimal retention and selectivity required to achieve your sample preparation objectives. The Development Microlute uniquely offers the user a choice of up to 12 different phases and sorbent loadings (10–100 mg) in a standard format 96-well plate. Constructed from a single piece of molded high-quality polypropylene, Development Microlute plates will not bend or distort because individual SPE cartridges do not have to be repeatedly plugged in and out. The sorbent slurry loading technique eliminates channeling effects that often limit the performance of dry powder loaded SPE columns. Each well has an individual drain spout ensuring 100 percent sample transfer and zero crossover contamination.
