Hoechst dyes are cell membrane-permeant, minor groove-binding blue fluorescent DNA stains. Hoechst dyes are widely used in cell cycle and apoptosis studies and also as nuclear counterstains. Biotium also offers Hoechst 33258, 10 mg/ml in dH2O (#40044). Hoechst 33258 and Hoechst 33342 are spectrally...

Aminooxy dyes have an aminooxy reactive group, which can be used to label a target molecule with an aldehyde or ketone group. An aminooxy group readily reacts with an aldehyde or ketone group to form a stable linkage without the use of a reducing agent. CF® dyes are Biotium's line of next-generation...

KE00019 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The IL-12 p70 ELISA kit is to be used to detect and quantify protein levels of endogenous IL-12 p70. The assay recognizes human IL-12 p70. An antibody specific for IL-12 p70 has been pre-coated onto the...

Oxazole Red, also known as YO-PRO®-3, is a bright, cell-impermeant, monomeric far-red nucleic acid dye (excitation/emission 612/631 nm). It is essentially nonfluorescent until bound to nucleic acids, making it a useful dead cell stain for microscopy or flow cytometry. 1 mM in DMSO.

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,...

Aminooxy reagents such as aminooxy-5(6)-FAM react with aldehydes or ketones to form a stable oxime linkage under mild conditions. Similar to ARP, aminooxy-5(6)-FAM can be used to label abasic sites in damaged DNA. It can also be used to label polysaccharides and glycoproteins....

ZeptoBlock is an immunoassay reagent formulated to block nonspecific binding sites of microwell plates to which antigen or antibody has been applied, thus minimizing interfering substances and cross-reactivity.

Heparin-binding EGF-like growth factor (HB-EGF) is a member of the EGF family of proteins that in humans is encoded by the HBEGF gene.HB-EGF-like growth factor is synthesized as a membrane-anchored mitogenic and chemotactic glycoprotein. An epidermal growth factor produced by monocytes and...

Detection kits for the VZV CE-IVD marked version available for in vitro diagnostic use Available in TaqMan format for analysis Varicella zoster virus (VZV) is one of eight herpes viruses known to infect humans and other vertebrates. VZV commonly causes chickenpox in children and both shingles and...

Detection kits for Pneumocystis jirovecii Available in TaqMan format for analysis Pneumocystis jirovecii is a yeast-like fungus that causes Pneumocystis jirovecii Pneumonia (originally known as Pneumocystis carinii Pneumonia or PCP). PCP is the most common opportunistic infection in patients with...

Human Leptin plays a key role in regulating energy intake and energy expenditure, including appetite and metabolism. It is one of the most important adipose derived hormones. The Ob (Lep) gene (Ob for obese, Lep for leptin) is located on chromosome 7 in humans. It is manufactured primarily in the...

GelStar™ Nucleic Acid Gel Stain is a highly sensitive fluorescent stain for detecting both DNA and RNA. You can choose to either add GelStar™ Stain to your agarose solution prior to casting or to post stain your gels. GelStar™ Nucleic Acid Gel Stain exhibits exceptional...

Single donor specimens collected from donors prior to and continuing through disease progression.

Cyanine 555-dUTP can be used to synthesize labeled DNA probes for in-situ hybridization, microarray or blotting techniques. Red fluorescent Cyanine 555 is structurally identical to Cy®3 and has excitation/emission at 555/565 nm). Cy dye is a registered trademark of GE Healthcare.

K10014 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The mouse IL-12 p70 ELISA kit is to be used to detect and quantify protein levels of endogenous mouse IL-12 p70. The assay recognizes mouse IL-12 p70. An antibody specific for mouse IL-12 p70 has been pre-coated...

BactoView™ Dead 600/615 is a novel deep-red fluorescent DNA dye for no-wash staining of dead bacteria. Unlike traditional dyes like PI that readily stain live gram+ cells, BactoView™ Dead dyes selectively stain dead cells in both gram+ and gram- strains. 500X in water, 100 uL.

The melanocortin family consists of five melanocortin G-Protein-coupled receptors (designated MC1-5R). The melanocortins, a-, ß- and ?-melanocyte-stimulating hormones (MSHs), are peptides derived from a precursor protein POMC, and play important roles in energy balance, reproductive function,...

Interferon-Alpha 2b (IFN-Alpha 2b) produced by leukocytes is a member of Interferon family. IFN-alpha is mainly involved in innate immune response against a broad range of viral infections. IFN-alpha 2 has three acid stable forms (a,b,c) signaling through IFNAR2. IFN-alpha 2b shares 99.4% aa...

3,6,9-Trioxaundecane-1,11-diyl dimethanethiosulfonate is a water soluble MTS cross-linker. Stock solutions made in anhydrous DMF are stable for at least two months if stored at -20°C. However, stock solutions made in water or buffer should be used immediately.        Off-white...

Enzyme linked immunoassay used to detect Human Immunodeficiency Virus Type 1 (HIV-1) p24 antigen in cell culture media Wells coated with a monoclonal antibody specific for the p24 gag gene product of HIV-1 Monitor the purification and biochemical behavior of HIV-1 Keep refrigerated between 2 to 8°C...

Programmed cell death protein 1, also known as PD-1 and CD279 (cluster of differentiation 279), is a protein that in humans is encoded by the PDCD1 gene. PD-1, functioning as an immune checkpoint, plays an important role in down regulating the immune system by preventing the activation of T-cells,...
