High-Throughput Fluorescence Imaging and Analysis of Spheroids

Introduction As cells do not grow in isolation, traditional two-dimensional (2D) cell culture monolayer models lack physiologically relevant environmental conditions and can have drastic differences in terms of their physical and biochemical features, compared to intact biological systems. Since more physiologically relevant animal studies are time consuming and expensive, there is a need for experimental models that span the gap between in vitro cell-based assays and in vivo animal studies.

Simplified workflow for Instant ELISA kits using the Multiskan Sky Microplate Spectrophotometer and Wellwash Versa Microplate Washer

This application note demonstrates the benefits of using the Invitrogen™ Human TNFα Instant ELISA™ Kit with the Thermo Scientific™ Multiskan™ Sky Microplate Spectrophotomer and Wellwash™ Versa™ Microplate Washer. In addition, we show how to streamline the workflow by incorporating a preprogrammed pipetting protocol developed with the My Pipette™ Creator app and a Thermo Scientific™ E1-ClipTip™ Bluetooth™ electronic pipette.

Plaque Assay

A cell monolayer is treated with a dilution of a GFP-expressing virus. The cells are then coated with agar, which limits the virus spread to only neighboring cells.After incubation, GFP+ circles of infected cellsare counted for virus titration.

Quantitation of monoclonal antibody infliximab in human plasma by LC-MS/MS using Fab-selective limited proteolysis nSMOL technology

Infliximab, known commercially as Remicade, is a chimeric IgG1 kappa monoclonal antibody (mAb) that targets tumor necrosis factor-alpha (TNF).
In studies conducted, a significant number of patients (30-40%) who did not respond to anti-TNF treatment were identified.
