| Description | EPQpYEEIPIYL, a phosphopeptide, is a Src homology 2 (SH2) domain ligand. EPQpYEEIPIYL activates Src family members (e.g. Lck, Hck, Fyn) by binding to SH2 domains[1][2] | β-Endorphin, human, a prominent endogenous peptide, existing in the hypophysis cerebri and hypothalamus, is an agonist of opioid receptor, with preferred affinity for µ-opioid receptor and δ-opioid receptor; β-Endorphin, human exhibits antinociception activity | The 50 bp DNA Marker is provided in a solution of 1× DNA Loading Buffer, which can be directly used for nucleic acid electrophoresis analysis. The 250 µL is defined as the base specification. All larger sizes correspond to incremental volumes of this base | DAMGO is a µ-opioid receptor (µ-OPR ) selective agonist with a Kd of 3.46 nM for native µ-OPR[1] | Neuromedin U, rat TFA is a 23-amino acid brain-gut peptide. Neuromedin U (NMU), through its cognate receptor NMUR2 in the central nervous system, regulates several important physiological functions, including energy balance, stress response, and nociception |
