Solutions to Advance Therapeutic Peptide Research

To date, over 60 peptide drugs have been approved worldwide; over 150 are in active clinical development. 

Although the first native peptides such as insulin and ACTH were isolated from mammalian tissues, most native peptides currently on the market are produced synthetically or through recombinant expression. Novel development strategies are focusing on the improvement of pharmaceutical properties of native and analog peptides such as half-life extension, oral bio-availability and intestinal permeability. 

Cell Analysis Platforms

By identifying new peptide drugs and small molecules that target peptide receptors high-throughput screening (HTS) and live cell analysis technologies offer unique solutions to accelerate the discovery process.

iQue® 3 High-Throughput Cytometry Platform

Built to Accelerate Your Research - Get from samples to actionable results in record time!

Assess multiple cellular parameters faster, with fewer cells using lower amounts of reagents. With high throughput sample processing and analysis, and the ability to simultaneously collect data on multiple parameters, the iQue® 3 is transforming biologics discovery by converting the low throughput, time consuming traditional flow cytometry approach into a truly advanced screening and profiling method with deeper, more efficient insight.

Incucyte® Live-Cell Analysis System

Gain insight into the cellular effects of your peptide drug candidate, directly from inside your incubator, with our real-time quantitative live-cell imager and analyzer.

The Incucyte® Live-Cell Analysis System is a real-time quantitative live-cell imaging and analysis platform that enables visualization and quantification of cell behavior over time, by automatically gathering and analyzing images around the clock within a standard laboratory incubator. This groundbreaking technology allows researchers to make time-lapsed, kinetic measurements from living cells over days and weeks providing insight into active biological processes in real time.

iQue® 3 High-Throughput Cytometry Platform

Qbeads® Plexscreen family of reagents use immunochemistry to capture specific secreted proteins on distinct bead types. We offer beads for human, mouse and rat secreted proteins.

Qbeads® Family of Reagents enable capture of specific proteins on distinct bead types for multiplexed quantitation of cytokines, adhesion molecules, enzymes, growth factors receptors and more.

Cellular Phenotype and Function Applications 
Mix-and-read screening kits include optimized reagents and flexible formats validated for the iQue platform. No wash protocols save time, reduce variability and allow for miniaturization. Kits can be multiplexed to increase assay content and reduce sample requirements.

Immune Cell-Based Kits enable the analysis of multiple immunological cell phenotypes and functional traits such as viability, proliferation, and cytokine release.

Incucyte® Live-Cell Analysis System

White Paper: Live-Cell Immunocytochemistry
Immunocytochemistry (ICC) is a powerful laboratory imaging technique for visualizing the location of specific proteins in cells using targeted fluorescently-labeled antibodies (‘immunofluorescence’). In this article, we introduce an integrated solution for ‘live-cell’ ICC, based on Incucyte® Live-Cell Analysis and fluorescently-labelled antibody fragments. The methodology is amenable to any protein expressed on the cell surface to which there is a corresponding specific antibody.

Morphological and Phenotypic Live-Cell Assays
Ensure the physiological relevance of results and reveal time-dependent treatment effects early in the drug discovery process by providing real-time morphological and phenotypic insight.

Cubis II - Your Balance, Your Way

Highest precision and safe workflows
Cubis II Laboratory balances offer attractive build-in – both hardware (e.g. calibration or leveling) and software (QApps) solutions, modularity and various connectivity options at the highest level of precision. These balances were designed for intuitive operation, aided by intelligent assistant systems which ensure the correct usage of the balance at all the time.

Ergonomic sample weighing with uncompromised accuracy
The great variety of sample holders and weighing pans ensure that samples of various types (e.g. safe-lock tubes, vials, flask, syringes or even animals) can be weighed directly on the balance. In this way workflows can be executed much easier, safer and faster. Made of titanium, not only the highest material quality is guaranteed, but notably the repeatability is not jeopardized because of the non-magnetic properties.
