Real-time and label free determination of ligand binding-kinetics to

• Real-time and label free determination of ligand binding-kinetics to primary cancer tissue specimens; a novel tool for the assessment of biomarker targeting

The paper describes use of Attana QCM label free methodology to study molecular binding kinetics in situ on FFPE tissues. FFPE tissue sections of human placenta tissues and prostate cancer were immobilised on COP-1 surfaces using ploy-L-lysine solution. Interaction between vAR2 protein and its receptor has been analysed using Attana Cell 200 system. Affinity value in the nanomolor range was detected for the interaction between rVAR2 and its receptor and no detectable binding was observed with the haelthy tissues.

Combined Bacteria Microarray and Quartz Crystal Microbalance

• Combined Bacteria Microarray and Quartz Crystal Microbalance Approach for Exploring Glycosignatures of Nontypeable Haemophilus influenzae and Recognition by Host Lectins

The paper describes the use of the Attana Cell 200 instrument to characterize the glycosignature of bacteria (haemophilus influeanze). The bacteria have been immobilized using a ConA-LNB surface. Different lectins injected and the binding kinetic analyze. Comparison of the frequency shift obtained using different strains confirm the result obtained in micro-array.

Facile fabrication of glycopolymer-based iron oxide nanoparticles and their applications in the carbohydrate–lectin interaction and targeted cell imaging.

• Facile fabrication of glycopolymer-based iron oxide nanoparticles and their applications in the carbohydrate–lectin interaction and targeted cell imaging.

A method for facile fabrication of carbohydrate-functionalized iron oxide NPs pre-coated with a glycopolymer was developed. The authors studied the binding affinities of these mannose and gluocose-functionalized NPS towards lectins immobilized on QCM chips (ConA, PNA or galectin-9) or on the surface of cells (colon cancer KM12 cells or Jurkat cells).

Quality Control and Purification of New Biological Pharmaceuticals

Participants - Astra Zeneca AB, Attana AB, Akzo Nobel Pulp and Performance Chemicals AB and Karlstad University and three more partners.

Thursday November 30th 2017 the project BIO-QC "Quality Control and Purification of New Biological Pharmaceuticals" was initiated. Biological pharmaceuticals are proteins or similar molecules, which mimics molecules in the body and are injected in the body to stimulate the immune system. To provide criteria’s for quality control of biological pharmaceuticals.

The project has a budget of approximately €2 million and includes seven different parties, Attana AB, AstraZeneca, Akzo Nobel Pulp and Performance Chemicals AB and Ridgeview Instruments AB and Karlstad University, Linné University and Örebro University.

NanoCarb: Development of glycosylated nanoparticles with enhanced therapeutic actions

Participants - Royal College of Surgeons in Ireland, University of Warwick, Università degli Studi di Milano, CIC biomaGUNE, Vlaamse Instelling voor Technologisch Onderzoek, Ludger Ltd, Midatech Pharma, Mario Negri Institute for Pharmacological Research.

The overarching aim of the NanoCarb ETN project is to develop glycosylated nanoparticles with enhanced therapeutic actions for healthcare applications. 15 Early Stage Researchers (ESRs) recruited for the NanoCarb project will work on their individual ESR projects designed to provide appropriate research goals for PhD students. Each ESR will be exposed to a well-balanced and optimal experience in academia, industry and research centre in order to increase their research experience and scientific maturity.

Nanoclassifier

NanoClassifier: QCM for rapid label-free Bionano interface evaluation and screening of effectiveness of nano-targeting strategies for therapeutics.

Participants - University College Dublin, Attana AB.

Nanomedicine and Nanosafety rely on the same fundamental interactions between the nanoparticle interface and the biological milieu surrounding it, and it is this “corona” of proteins and other biomolecules that form at the bionanointerface that determines the fate and behaviour of nanomaterials. Understanding, classifying and predicting nanoparticle coronas from their physicochemical properties offers a novel approach to screening for toxicity at early stages of product development and for regulatory purposes.

Application notes

Kinetic & Affinity Characterization – Polyclonal Antibodies

• Kinetic & Affinity Characterization – Polyclonal Antibodies

 

The primary goal of antibody production is to obtain high titer, high affinity antiserum for use in experimentation, diagnostic tests or therapy. Detection and monitoring of the purification of these polyclonal antibodies can be time consuming and troublesome. This Application Example demonstrates how the Attana C-Fast system can be used to rapidly characterize polyclonal antibodies raised against peptides and protein antigens. Polyclonal antibodies are by nature a mixture of antibodies, with their own respective kinetic characteristics and most probably also with differences in antigen epitope specificities. Due to this heterogeneity, the rate constants derived and the calculated affinity should be regarded as a mean of the different subpopulations.

• Crude Samples Analysis; Screening and Characterization of Hybridoma Supernatants

 

Purification, and sometimes labelling of antibodies before characterization of the antibody-antigen interactions can be very time consuming and associated with issues such as optimization and yield. The Attana system together with the Attana IgG capture kits can reduce these problems. Here we demonstrate an anti-mouse IgG surface with the ability to capture antibodies from crude materials, followed by a detailed study of the kinetics for the interactions between the antibody and its antigen.
