Introduction We are interested in exploring whether certain types of extracellular vesicles (EVs) may be more likely to become trapped while crossing the blood-brain barrier (BBB). Specifically, we are curious if EVs possessing certain types of surface integrins might bind…
Introduction As what we’ve learned from the previous “Catch-and-Display Immunoassay” (CAD-IA) trials, we switched to an antibody pair from OriGene with low non-specific binding ability to each other and start to conduct ultracentrifugation for all reactive reagents for the reduction…
Author: Kevin Ling Dysfunction of the outer retinal blood barrier (oRBB), which is composed of the retinal pigment epithelium (RPE), Bruch’s membrane, and choriocapillaris (CC), is implicated in age-related macular degeneration (AMD), which causes irreversible central vision loss [1-4]. AMD…
Introduction: In the previous post, we demonstrated our capability to fabricate the nano-pocket membrane and effectively capture and release particles of various sizes. In this post, our focus shifts to exploring the membrane capability. We will focus on the membrane…
Towards Surface Enhanced Raman Functionalization of Nanopocket membranes Introduction Use of Raman microscopy is used to evaluate the chemical profile of substances. Surface enhanced Raman spectroscopy (SERS) is a signal-boosting techniques where the weak Raman signal is amplified through…
Introduction The Ehler-Danlos Syndromes are a group of thirteen heritable connective tissue disorders. These disorders are genetic, and usually involve a mutation in genes that code for components in the collagen matrix (1). Some of the main characteristics in patients…
Introduction This post will describe the preliminary work I have completed using size exclusion chromatography (SEC) for EV enrichment. We are ultimately interested in interrogating serum EV biomarkers using CAD-LB, however, the presence of protein and lipoprotein contaminants reduces the…
Introduction This post provides an update on a series of experiments conducted with Sam. These experiments were designed to assess the versatility of the CAD-LB platform for detecting EVs in urine samples. Urine is a complex biofluid often used in…
For year one of the Trace grant, I will be focusing on the development of a standard operating procedure for the uSiM-CA. To begin this process, I am transferring all of my current operating procedures from the Andor dragonfly confocal…
Introduction: Developing innovative therapeutics and treatment approaches with improved effectiveness and safety necessitates the use of cell co-culture models and barrier environments that mimic in vivo conditions. These models involve culturing two or more cell types together in vitro, allowing…
