At Fluxion, we’re passionate about delivering cell-based and cell-free solutions that facilitate the transformation of research discoveries into new ways to diagnose and treat patients. By characterizing molecular and cellular mechanisms of disease, Fluxion’s platforms help bridge the translational medicine gap, enabling rapid advances in disease research, drug discovery, and the development of diagnostic tests.

Rheumatology

and autoimmune disease

Inflammation plays a large role in rheumatic diseases, whether it be gout, lupus, or rheumatoid arthritis (RA). With systemic autoimmune rheumatic diseases (SARD), white blood cells mistakenly attack the body’s own tissues, leading to inflammation. In order to fully understand inflammation in these circumstances, each step of the process needs to be analyzed in a controlled environment.

The BioFlux system is an easy to use, automated platform for investigation of rheumatic disease under shear flow and high throughput. Immune cell rolling, adhesion, aggregation, and activation can all be studied with BioFlux. Analyzing these processes under shear flow is crucial to maintain physiological relevance and mimic behavior in the vasculature.

(A) Anticoagulated blood was labeled with calcien AM and incubated with different concentrations of GS-9876, and perfused through collagen-coated channels at 10 dynes/cm^2. (B) GS-9876 was shown to block platelet adhesion and aggregation (Di Paolo et al., 2018).

Key BioFlux Advantages For Rheumatology Studies

  • Study live immune cell adhesion and rolling in a physiologically-relevant assay

  • Utilize time-lapse microscopy under flow and post-experiment image analysis to determine immune cell rolling distance

  • Calculate area of immune cell adhesion by utilizing BioFlux software analysis capabilities

  • Investigation of platelet and neutrophil adhesion and aggregation on different substrates over many parallel conditions
