Corona quick test

4. June 2020

NHD & partners start multi-million project

Early tracing of SARS-CoV2-infected individuals at the stage when there are no clinical symptoms, is crucial to prevent further transmission.

Based on existing platform technology NH DyeAGNOSTICS with  scientific and industrial partners are developing a test for rapid, portable SARS-CoV2 diagnostics.

.

Why is the development of the quick test particularly important?

  • • allows to perform quick and cost-efficient point-of-care testing
  • • allows regular screening in the groups of high-risk individuals
  • • simple stripe-test, does not require specialized expensive machines,

reagents or trained staff

.

In alliance with our cooperation partners we expect to bring the product to the market within 6-8 months. The project is co-funded by the BMBF.

About MS

Mass spectrometry in proteomics

In proteomics, mass spectrometry is applied to characterize and sequence proteins. Over the last decades, it has become an indispensable technique. Its development over the last decades has led to three fundamental applications: determining protein interaction, categorizing protein expression and locating protein modification.

Mass spectrometry in pharmacology

In pharmacology, mass spectrometry is applied for drug discovery to determine the structure of drugs and metabolites and for screening metabolites in biological systems.

Tandem Mass Spectrometry (MS/MS)

Tandem mass spectrometry involves a tandem mass spectrometer. The sample undergoes ionization and mass-charge ratio separation in the first stage of mass spectrometry (MS1). Then, selected ions of the articular mass-charge ratio are fragmented to generate product ions for detection in the second stage of mass spectrometry (MS2).

Tandem mass spectrometry gives additional information about the selected ions. It is typically applied to sequence proteins and oligonucleotides because the fragments analyzed can be compared to peptides or nucleic acid sequences found in databases.

Western Blot: What happens to my protein?

31. May 2019

Monitoring and Normalization of Sample Protein

The immunochemical detection of specific proteins by Western Blot analysis is performed by different steps including: protein extraction, separation, transfer, blocking, antibody incubation, washing, target detection.

The protein transfer rate is less than 100%. Transferred proteins are not covalently bound to the blotting membrane. Therefore, the amount protein of each sample is continuously decreased (see figure below). The loss of protein is caused by different sources (e.g. hydrophobicity, mechanical shearing forces,...).

Valid Normalisation of Western Blots

The patented Smart Protein Layers (SPL) technology offers you the easy but sensitive detection of sample protein  during all stages of the Western Blot procedure. The precise detection of sample amount present on the blot at the same time the target is immunodetected allows for the accurate normalisation of target protein expression.

Patented SPL Technology

The corresponding SPL kit comes with fluorescent SPL label which rapidly bind to the sample protein prior electrophoresis. Depending on sample properties two different workflows can be used.

.

SPL EASY workflow
Very easy usage of the SPL kit  limited to samples within a range of 25μg - 75μg of extracted total protein.

SPL ADVANCED workfow
Advanced usage of the SPL kit for scarce samples and/ or particular buffer compositions. This approach provides further information about the sample, the labeling reaction and monitors the complex WB workflow.

Both the easy and advanced workflow offer precise protein transfer monitoring and allow for experiment-to-experiment comparisons.
