Establishment of human models of the blood-brain barrier (BBB) can benefit research into brain conditions associated with BBB failure. We describe here an improved technique for preparation of a contact BBB model, which permits coculturing of human astrocytes and brain endothelial cells on the opposite sides of a porous membrane.

A procedure for making en face preparations of the mouse carotid artery and aorta is described. Such preparations, when immunofluorescently stained with specific antibodies, enable us to study localization of proteins and identification of cell types within the entire vascular wall by confocal microscopy.

This protocol describes a detailed method for efficient generation of integration-free iPSCs from human adult peripheral blood cells. With the use of four oriP/EBNA-based episomal vectors to express the reprogramming factors, KLF4, MYC, BCL-XL, or OCT4 and SOX2, thousands of iPSC colonies can be obtained from 1 mL of peripheral blood.
FAQs
Anticoagulation keeps blood from clotting before separation, helping the starting sample remain workable for downstream preparation. This step matters because clot formation can alter the distribution and recovery of blood-cell populations, making later measurements less consistent. In immunology and infection studies, reliable anticoagulated material supports comparisons of immune-cell abundance, cellular function, pathogen interactions, and inflammatory responses.
Density-gradient separation exploits differences in cell density so selected populations can be separated during centrifugation. The resulting fractions can be used when an experiment requires a more defined cellular starting material than untreated blood. This approach is especially relevant when investigators need to examine immune-cell abundance or function without treating all blood components as one mixed sample.
Selective red blood cell lysis takes advantage of differences in membrane sensitivity between erythrocytes and other blood cells. Removing red cells can make leukocyte-focused preparations more suitable for downstream analysis while retaining the populations of interest. The balance is important: preparation must reduce unwanted erythrocyte content without compromising cell viability, because damaged cells can affect functional or infection-related measurements.
Washing steps help clean the selected fraction after separation or lysis and support a more consistent preparation for analysis. Their value is not simply removal of visible material; washing is part of maintaining a usable cell suspension while limiting preparation-related effects on viability. This consistency improves the interpretation of flow cytometry, microscopy, and immunological assays.
A typical workflow can begin with anticoagulated blood, followed by centrifugation and, when appropriate, density-gradient separation. Selective red blood cell lysis and washing may then refine or clean the recovered population. The combination depends on whether the goal is prepared whole blood, peripheral blood mononuclear cells, leukocytes, or erythrocytes, as well as the planned experiment.
Prepared whole blood, peripheral blood mononuclear cells, leukocytes, and erythrocytes can each serve as experimental starting materials, depending on the planned analysis or experiment. Across these formats, the source material identifies applications in immunological assays, flow cytometry, microscopy, and infection studies, including assessment of cellular responses and pathogen interactions.
Consistent preparation is important because differences introduced before measurement can influence apparent immune-cell abundance or function. In infection research, the same principle applies to studies of pathogen interactions and inflammatory responses; in treatment studies, it supports comparison of effects across samples. Preparation quality therefore contributes to reproducible interpretation rather than serving only as a preliminary cleanup step.
