    CHOLERA TOXIN SUBUNIT B 原装正品
    产品: invitrogen
    货号: C34775
    规格: 100 UG
    名称: Cholera Toxin Subunit B (Recombinant), Alexa Fluor 488 Conjugate
    Molecular Probes® cholera toxin conjugates are made from a recombinant version of the B subunit only. This allows us to provide a very high-purity product that is completely free of the toxic A subunit. Cholera toxin B subunit (CT-B) attaches to cells by binding to ganglioside GM1, making it a powerful tool for retrograde labeling of neurons. This tracer has been used in a variety of applications, including tracing of rat forebrain afferents, projections of the parabrachial region, and neurons of the urinary bladder wall. When used in neuronal tracing applications, CT-B is typically introduced by pressure injection or by iontophoretic injection into neural tissue.
    Cholera Toxin Subunit A Specifications:
    • Label (Ex/Em): Alexa Fluor® 488 (495/519 nm)
    • At neutral pH, the 11.4 kDa B subunit exists as a 57 kDa pentamer
    • Lyophilized product can be dissolved in buffer (e.g., PBS) for use
    For Research Use Only. Not for any animal or human therapeutic or diagnostic use.
