Inkt Cell Isolation

iNKT cell isolation is the process of separating invariant natural killer T cells from blood or tissues for controlled immunological study, enabling researchers to examine lymphocytes that link innate and adaptive immunity. The workflow can combine sample preparation, density-based separation, antibody-mediated magnetic enrichment, and flow-cytometric identification or sorting using the invariant T-cell receptor and natural killer cell markers. Isolated iNKT cells can be analyzed for cytokine production, activation, cytotoxicity, and interactions with antigen-presenting cells during infection. This approach supports research into microbial immunity, inflammation, cancer immunology, and the development of iNKT-directed diagnostics or therapies.

Analysis of rodent cerebrovascular anatomy plays an important role in experimental stroke research. In this context, intravascular perfusion with colored latex has been considered as a standard tool for several years. However, this technique implies distinct technical limitations, which undermine its reproducibility. Here, we describe a simple method to visualize cerebral vessels in a reproducible manner. Injection of a mixture of two commercially available carbon black inks through the left...
