Separating Protein with SDS-PAGE

2023
Sodium Dodecyl Sulfate Poly-Acrylamide Gel Electrophoresis, or SDS-PAGE, is a widely-used technique for separating mixtures of proteins based on their size and nothing else. SDS, an anionic detergent, is used to produce an even charge across the length of proteins that have been linearized. By first loading them into a gel made of polyacrylamide and then applying an electric field to the gel, SDS-coated proteins are then separated. The electric field acts as the driving force, drawing the SDS...

SDS-PAGE

2023
Gel electrophoresis is a method that separates biological macromolecules like nucleic acids or proteins by forcing them to pass through a gel matrix under an electric field. A variation of gel electrophoresis, termed polyacrylamide gel electrophoresis (PAGE), is commonly used for separating proteins according to their molecular size by passing them through a polyacrylamide gel. Because of the varying charges associated with amino acid side chains, PAGE can be used to separate intact proteins...

2025
This video describes an antegrade perfusion technique of an isolated mouse heart during which a perfusate is injected through the left ventricle, and eventually, it perfuses the entire myocardium. This method can be used to isolate cardiomyocytes from murine models and generate decellularized hearts for further downstream applications.

Langendorff Retrograde Heart Perfusion: An Ex Vivo Technique to Perfuse Isolated Mouse Heart
0 Views •
2025
In this video, we perform Langendorff retrograde perfusion of an isolated mouse heart. During the procedure, the cardiac activity of the heart is maintained by perfusing it retrogradely with a perfusion solution via the coronary arteries using a cannula inserted into the ascending aorta. The model is used to study the cardiac pathophysiology of the heart.
FAQs
Its key action is detergent-mediated membrane disruption. SDS interacts with lipid bilayers and solubilizes cellular material, reducing cellular background while leaving key structural components available for examination. This distinction matters because the goal is not simply to remove tissue contents: it is to expose extracellular matrix architecture sufficiently for structural analysis and three-dimensional visualization.
Vascular delivery allows the solution to move through an intact organ or tissue specimen rather than contacting only an exposed surface. That route links reagent distribution to the specimen’s existing vascular network, making delivery conditions an important determinant of processing consistency. It also helps explain why preserved architecture and effective cellular reduction must be evaluated together.
Detergent exposure helps determine how effectively cellular material is solubilized, but the final outcome also depends on preserving tissue structure. Consequently, exposure conditions should be considered alongside delivery conditions rather than treated as an isolated variable. The relevant outcome is a preparation with reduced cellular background and sufficiently retained architecture for the intended analysis.
A basic workflow circulates sodium dodecyl sulfate solution through the vascular network of an intact organ or tissue specimen. The processed material is then assessed for the extent of cellular background reduction and the preservation of structural components. These observations determine whether the preparation is suitable for visualization, structural analysis, or subsequent scaffold-oriented work.
Preparations produced through this approach can support three-dimensional imaging and analysis of tissue structure because reduced cellular background improves visibility of extracellular matrix architecture. They can also contribute to development of biological scaffolds. Thus, the method is useful when researchers need to examine or use preserved tissue organization rather than cellular contents alone.
In a biology context, the method supports clearing by reducing cellular background while retaining key structural features. This combination improves the visibility of extracellular matrix architecture in tissue specimens, allowing researchers to examine organization in three dimensions. Interpretation still requires attention to processing conditions, since detergent exposure, delivery, and structural preservation influence the resulting preparation.
