For some applications, 5-(and-6)-carboxyrhodamine (5(6)-CR 110) is a superior alternative to the widely used green fluorescent dye 5-(and-6)-carboxyfluorescein. The dye is insensitive to pH between 4 and 9 and is much more photostable than fluorescein.    ...

Eosin-5-maleimide is a good photosensitizer and can be used to selectively label thiols. It has a quantum yield of 0.57 for singlet oxygen generation, which makes it useful for photoconversion of electron-rich materials such as diaminobenzidine (DAB) or fluorescent dyes into highly electron-dense...

Cholecystokinin (CCK)-A and CCK-B receptors are highly homologous members of the seven transmembrane domain G-protein-coupled receptor super-family.

Human Granulocyte Macrophage Colony Stimulating Factor (hGM-CSF), a hematopoietic growth factor, is mainly involved in granulopoiesis and monocytopoiesis. It is produced by T-cells and macrophages in response to antigens, and by endothelial cells and fibroblasts following induction of...

10 mM Stabilized dNTP mix (HS dNTP Mix) is suitable for use in PCR, sequencing, nick translation, fill-in, cDNA synthesis, TdT tailing reactions, and dilution of radiolabeled dNTPs. These nucleotides are supplied as convenient, ready-to-use solutions at a concentration of 10 mM in Tris-HCl (pH 7.5)....

PreScission Protease is a fusion protein of glutathione S-transferase (GST) and human rhinovirus (HRV) type 14 3C protease . The protease specifically recognizes a subset of sequences which include the core amino acid sequence Leu-Phe-Gln/Gly-Pro cleaving between the Gln and Gly residues . Substrate...

Fluorescent conjugates of Alpha-Bungarotoxin bind to the nicotinic acetylcholine receptor with high affinity, and thus can be used to image the distribution of the receptor at the neuromuscular junctions. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness,...

KE00213 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The CCL17/TARC ELISA kit is to be used to detect and quantify protein levels of endogenous CCL17/TARC. The assay recognizes human CCL17/TARC. An antibody specific for CCL17/TARC has been pre-coated onto the...

Macrophage Colony-Stimulating Factor 1 (M-CSF) , involved especially in monocytopoiesis, [1] is a hematopoietic growth factor. In mammals, it exits three isoforms, which invariably share an N-terminal 32-aa signal peptide, a 149-residue growth factor domain, a 21-residue transmembrane region and a...

The adaptor is for use with Novex XCell I, II & SureLock® gel tanks when running ExpressPlus™ or SurePAGE™ gels (8x10cm), see gel manual for detail.

Anti-HIV-1 RT Clone 39/4.12.2 exhibits reactivity using Western blotting and ELISA. Antibody dilutions should be prepared using buffers containing suitable protein in order to stabilize antibody activity.

Proheparin-binding EGF-like growth factor (HB-EGF), also known as DTR, DTS and HEGFL, is a member of the EGF family of mitogens. It is expressed in macrophages, monocytes, endothelial cells and muscle cells. HB-EGF signals through the EGF receptor to stimulate the proliferation of smooth muscle...

Single donor specimens collected during the course of infection progression.

Neuropeptide Y (NPY) is a vasoconstrictor and a brain peptide that inhibits Ca 2+ -activated K + channels in vascular smooth muscle. Neuropeptide Y (NPY) is implicated in the control of blood pressure, sexual behavior, and food intake. Neuropeptide Y (NPY) inhibits cholecystokinin- and...
