This video describes SEC-MALS, which leverages the abilities of size-exclusion chromatography (SEC) and multi-angle light scattering (MALS). In SEC-MALS, the SEC separates proteins or protein complexes based on their size, and the MALS detector determines the average molecular weight by measuring the intensity of the light scattered by the molecule at different angles.

Lensfree optical tomography is a three-dimensional microscopy technique that offers a spatial resolution of <1 μm × <1 μm × <3 μm in x, y and z dimensions, respectively, over a large imaging-volume of 15-100 mm3, which can be particularly useful for integration with lab-on-a-chip platforms.

Described here is a stereotactic procedure that can target challenging and difficult-to-reach brain regions (due to spatial limitations) using an angled coronal approach. This protocol is adaptable to both mouse and rat models and can be applied to diverse neuroscientific applications, including cannula implantation and microinjections of viral constructs.

In order to understand the pathophysiology of stroke, it is important to use reliable models. This paper will describe one of the most frequently used stroke models in mice, termed the middle cerebral artery occlusion (MCAo) model (also termed the intraluminal filament or suture model) with reperfusion.
FAQs
Changing the imaging perspective reveals arterial relationships that may be obscured in a single projection. Clinicians can compare the vessel lumen, branch points, and vessel course from different angles, then adjust the catheter or needle trajectory to match the anatomy more closely. This can make navigation more controlled and reduce uncertainty when the pathway is complex.
Tortuous vessels and branching anatomy can appear misleading when assessed from only one direction. Multiple angles help clarify how the artery curves, where branches arise, and how the lumen is oriented. That information supports better alignment between the instrument and vessel pathway, allowing clinicians to adapt their approach to individual anatomical variation rather than relying on a single view.
A single projection provides limited anatomical information and may leave the true vessel course or branch relationships uncertain. A multi-angle arterial approach adds complementary perspectives, allowing clinicians to assess alignment and anatomy from more than one direction. The broader view can support more deliberate catheter or needle positioning when a vessel is difficult to interpret or access.
The approach combines changes in imaging perspective with corresponding adjustments in instrument trajectory. Clinicians examine the arterial anatomy, identify the relevant lumen and branches, and modify the catheter or needle direction to improve alignment. This strategy can be incorporated into diagnostic angiography or endovascular intervention when the initial view does not adequately clarify the access path.
Clinicians may consider it when arterial pathways are complex, tortuous, or difficult to access through a single projection. It is relevant to diagnostic angiography and endovascular interventions in which accurate understanding of the vessel course affects navigation or treatment planning. The method is particularly useful when individual vascular variations make a standard approach less informative.
Multiple perspectives can clarify the arterial lumen, branching pattern, vessel course, and relationship between anatomy and the planned instrument trajectory. This information helps clinicians assess how to navigate the pathway and adapt decisions to the patient’s vascular variation. In diagnostic and interventional settings, the resulting anatomical understanding can support more controlled access and treatment planning.
