MCE Mouse CD4+ CD25+ Regulatory T Cell Positive Selection Kit is designed for the isolation of CD4+ CD25+ regulatory T cells (Tregs) from mouse splenic single-cell suspensions. The kit utilizes a two-step isolation strategy. First, CD4 Enrichment Beads are used to deplete non-target cells and enrich CD4+ T cells. Subsequently, CD25 Capture Antibody specifically binds to CD25+ cells, which are then captured by Releasable Magnetic Beads. Following isolation, the magnetic beads are gently detached from the cell surface using Magnetic Beads Release Buffer, yielding label-free CD4+ CD25+ regulatory T cells with no residual magnetic beads.

Research Areas:
BG-PEG-NH2 (SNAP-PEG-NH2) is an amino-terminal fluorescent probe building block and a precursor for site-specific labeling of SNAP-tag fusion proteins. BG-PEG-NH2 undergoes one-step coupling with activated carboxyl esters to form customized SNAP-tag substrates, which covalently bind to SNAP tags via a thioether bond formed at the Cys145 site. After coupling with a caged carboxyfluorescein, BG-PEG-NH2 forms a probe with Ex/Em = 500/524 nm following ultraviolet uncaging. Coupling of BG-PEG-NH2 with SeTau-647-NHS enables visualization of GPCR signal transduction. BG-PEG-NH2 is suitable for coupling reactions in aqueous phases or buffers, conjugation of labels, and labeling of intracellular or cell-surface proteins .
