In Vitro Diagnostics

IVD Fluorescent Dyes
In vitro diagnostics (IVD) are tests on samples such as blood, tissue or urine that have been taken from the animal or human body. IVD can detect diseases or other conditions and can be used to monitor a person’s overall health to help cure, treat, or prevent diseases. IVD enables to provide rapid test results, to simultaneously perform multiple tests, to detect customizable specific markers, to easily record data, and to quickly repeat the test for confirm. IVD may also be used in precision medicine to identify patients who are likely to benefit from specific treatments or therapies. BioActs offers a series of FSD Fluor dyes for effective IVD analysis.

Fluorescent Polystyrene Beads
Flamma® PS bead series are fluorescent spherical particles in the colloidal size made up of high-grade polystyrene (PS) doped with our proprietary dyes. Polystyrene beads are not cytotoxic, and they diffuse minimally from the injection site and persist for long periods in nerve cells. Our fluorescent beads display excellent optical properties yet negligible photobleaching under the intense excitation for fluorescence microscopy. The intense fluorescence and spherical shape of Flamma® PS bead series enable to generate stronger signals with small amount of probes in many tracing experiments. To decrease nonspecific binding and provide additional functional groups for conjugation, exteriors of PS bead are equipped with carboxylic acids. These pendent carboxylic acids allow them suitable for covalent coupling of proteins and other amine-containing biomolecules by using water-soluble coupling reagents. BioActs provides various sizes of Flamma® PS bead series (0.1 – 0.5 μm) in order to meet the diverse needs of our customer, and sizes specified in the product names are nominal bead diameters. These effective fluorescent PS beads can be utilized in a variety of applications such as neuronal tracers, cellular antigen markers, cell tracers, and the standardization reagents for flow cytometry. Due to their high fluorescence intensity, Flamma® PS bead series are suitable for the many nanoparticle based diagnostic tests, including tracking particles and cells, tracing fluid dynamics, discriminating the size dependence of uptake or transport in vivo. Although limited sizes of our fluorescent beads are available, we can prepare custom-sized particles, custom-dyed or custom-surface modifications orders upon request. Please contact our custom service for further information.

Magnetic Nanoparticles
BioActs Magnetic Nanoparticles are coated with silica polymer, affording biocompatibility, and can be used in a wide range of biological and biomedical fields such as cell separation, drug delivery, DNA extraction and protein purification. The strong magnetism of particles allows excellent dispersion, fast reaction and separation, low background signal. In order to conjugate with biomolecules such as DNA, RNA, protein, antibody, etc., the surface of magnetic nanoparticle is functionalized with alcohol, amine and carboxylic acid.  BioActs Magnetic Nanoparticles can be utilized in medical diagnostic, medical research, and therapeutic purpose.
