Biological Activity

Penitrem A is a potent and selective blocker of BKCa (KCa1.1) channels (IC50 values are 6.4 and 64.4 nM for BKCa channels containing α subunits only, and those containing α and β1 respectively). Displays no effect on native delayed rectifier K+ and KATP currents, or cloned KV1.5 channels. Blocks BKCa channels in both inside-out and cell-attached patches. Shown to enhance smooth muscle contraction in vitro and increase total peripheral resistance in vivo.

PCL-PEG-MAL

PCL-PEG-MAL is an amphiphilic block copolymer consisting of polycaprolactone (PCL), polyethylene glycol (PEG) and maleimide (MAL) functional groups. PCL-PEG-MAL is used in targeted delivery systems, surface modification of nanomaterials, functionalisation of biomaterials and biosensing technologies for specific chemical linkages or biomolecular immobilisation.

DSPE-PEG-Streptavidin

DSPE-PEG-Streptavidin is an important biocoupling molecule widely used in biomedical research, especially in drug delivery, targeted therapies, immunodiagnostics and biosensors. Through the specific binding between streptavidin and biotin, DSPE-PEG-Streptavidin can help to achieve efficient loading and targeted action in targeted delivery systems. In addition, the molecule is widely used in molecular imaging and bioassays, especially for molecular recognition using the strong affinity between streptavidin and biotin in assay platforms that require high sensitivity and specificity.
