Overview

Easily and efficiently isolate highly purified human basophils from HetaSep?-processed human peripheral blood samples by immunomagnetic negative selection, with the EasySep? Human Basophil Isolation Kit. Widely used in published research for more than 20 years, EasySep? combines the specificity of monoclonal antibodies with the simplicity of a column-free magnetic system.

In this EasySep? negative selection procedure, unwanted cells are labeled with antibody complexes and magnetic particles. The following unwanted cells are targeted for removal: neutrophils, eosinophils, T cells, B cells, monocytes, NK cells, dendritic cells, erythroid cells, and progenitor cells. The magnetically labeled cells are then separated from the untouched desired basophils by using an EasySep? magnet and simply pouring or pipetting the desired cells into a new tube. Following magnetic cell isolation in as little as 13 minutes, the desired basophils are ready for downstream applications such as flow cytometry, culture, or DNA/RNA extraction.

The isolation kit is compatible with cells that have undergone red blood cell depletion using HetaSep? (Catalog #07906).

This product replaces the EasySep? Human Basophil Enrichment Kit (Catalog #19069) for even faster cell isolations.

Data Figures

Figure 1. Typical EasySep? Human Basophil Isolation Profile

Starting with HetaSep?-processsed human peripheral blood, the basophil content (CD45+CD123+IgE+) of the isolated fraction is typically 94.0 ± 2.5% (mean ± SD using the purple EasySep? Magnet). In the above example, the purities of the start and final isolated fractions are 0.86% and 95.6% (gated on CD45+), respectively.

miR-3934 regulates the apoptosis and secretion of inflammatory cytokines of basophils via targeting RAGE in asthma. L. Dou et al. Allergy, asthma, and clinical immunology : official journal of the Canadian Society of Allergy and Clinical Immunology 2022 aug

Abstract

BACKGROUND Several miRNAs are now known to have clear connections to the pathogenesis of asthma. The present study focused on the potential role of miR-3934 during asthma development. METHODS miR-3934 was detected as a down-regulated miRNA in basophils by sequencing analysis. Next, the expression levels of miR-3934 in peripheral blood mononuclear cells of 50 asthma patients and 50 healthy volunteers were examined by RT-qPCR methods. The basophils were then treated with AGEs and transfected with miR-3934 mimics. The apoptosis levels were examined by flow cytometry assay; and the expression levels of cytokines were detected using the ELISA kits. Finally, the Western blot was performed to examined the expression of key molecules in the TGF-$\beta$/Smad signaling pathway. RESULTS miR-3934 was down-regulated in the basophils of asthmatic patients. The expression of the pro-inflammatory cytokines IL-6, IL-8 and IL-33 was enhanced in basophils from asthmatic patients, and this effect was partially reversed by transfection of miR-3934 mimics. Furthermore, receiver operating characteristics analysis showed that miR-3934 levels can be used to distinguish asthma patients from healthy individuals. miR-3934 partially inhibited advanced glycation end products-induced increases in basophil apoptosis by suppressing expression of RAGE. CONCLUSION Our results indicate that miR-3934 acts to mitigate the pathogenesis of asthma by targeting RAGE and suppressing TGF-$\beta$/Smad signaling.
