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 G M1 , 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 introduc...

In collaboration with Nexins Research BV, we provide the best and brightest annexin V conjugates available, including this FITC annexin V conjugate. Highly fluorescent annexin V conjugates provide quick and reliable detection methods for studying the externalization of phosphatidylserine, one of the earliest indicators of apoptosis.

Lectin phytohemagglutinin-L (PHA-L) is strongly inhibited by N-acetylglucosamine β(1-2) mannopyranosyl residues.[ALTREF PN29369] This lectin has been shown to agglutinate leukocytes and induce mitogenic activity in T-lymphocytes[ALTREF PN29369,PN29368] and has also been used as an anterograde tracer for the study of neuronal pathways.[ALTREF PN20284]

Wheat germ agglutinin (WGA) is one of the most widely used lectins in cell biology. Our Qdot(R) 655 conjugate of WGA exhibits the extremely bright and photostable fluorescence of the Qdot® 655 nanocrystal. Qdot® 655 WGA binds to sialic acid and N-acetylglucosaminyl residues.

Actin is an important tool for investigating cytoskeleton dynamics in-vivo . This highly purified actin from rabbit muscle is subjected to depolymerization and subsequent polymerization to ensure that the actin is able to assemble properly. The actin that polymerizes is then separated from remaining monomeric actin by centrifugation, depolymerized and packaged in monomeric form.

Labeled dextrans are hydrophilic polysaccharides most commonly used in microscopy studies to monitor cell division, track the movement of live cells, and to report the hydrodynamic properties of the cytoplasmic matrix. The labeled dextran is commonly introduced into the cells via microinjection. Dextran Specifications : Label (Ex/Em): Rhodamine B (570/590) Size: 70,000 MW Charge: Zwitterionic Fixable: Nonfixable High Manufacturing Standards of Molecular Probes® Dextrans We offer more than 50 fluorescent and biotinylated dextran conjugates in several molecular weight ranges. Dextrans are hydrop...
