Sample PreparationSample preparation can improve the quality and speed of separation techniques. Products to assist sample preparation include filtration equipment, evaporators, membranes and sieves.AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.High-Throughput ScreeningHigh-throughput screening (HTS) is an automated drug discovery technique for identification of active compounds against a compound library. Use HTS readers and integrated assay preparation / analysis workstations to screen your compounds. Identify active compounds against various HTS libraries, including membranes, proteins and peptides and HTS cell lines.

Useful system features include high-throughput, automation, robotic arms, automated liquid handling and associated database systems. Accessories in sample management include barcode scanners, heat sealers and tubes.Protein PurificationProtein purification is a vital step in drug discovery, therapeutics, biotech and life science research. The purification process typically involves subcellular or membrane protein extraction with cell lysis kits, separation of proteins from cell debris by filtration or spin columns, and the isolation of proteins of interest from other proteins and impurities with affinity purification (including fusion protein tags and antibody binding proteins A, G and L), immunoprecipitation or chromatographic methods, such as ion exchange, size exclusion and immobilized metal affinity chromatography. All purification methods come in multiple formats for your laboratory needs, including agarose or magnetic beads, resins, columns and filter plates.

Biopharmaceuticals may be produced from cell lines, plants, or microbial cells. Important considerations of biopharmaceutical use include application, cost, production process and purification.Thermal Analysis EquipmentThermal analysis equipment is used for measuring heat flow, weight loss, dimension changes or thermomechanical properties and is important for analyzing a material’s performance and stability. Thermal analysis equipment includes differential scanning calorimeters (DSC), thermogravimetric analyzers (TGA), thermomechanical analyzers (TMA), dilatometers, thermometers, vapor sorption analyzers, boiling and melting point apparatus. Thermal analyzers can reveal properties such as melting, crystallization and glass transitions or other processes such as oxidation, decomposition, volatilization, as well as coefficients of thermal expansion and modulus.

This potential is identified when compounds have the desired effect, such as interaction with a target protein, during high throughput screening.Drug DeliveryDrug Delivery refers to dosage form, route of administration, formulations, technologies, and systems for transporting a pharmaceutical compound in the body as needed to safely achieve its desired therapeutic effect. Drug delivery is often approached via the biopharmaceutical or small molecule drug's formulation, but it may also involve medical devices or drug-device combination products. Considerations include instrumentation, software and services. Monoclonal AntibodiesMonoclonal antibodies (mAbs) are lab-made molecules that can bind to specific antigens on cells, making them highly effective in treating cancers, autoimmune diseases, and infections.
