Evaluate the performance of nucleic acid tests for determination of the presence of HIV-1 nucleic acids Formulated with purified, intact organisms Organisms are chemically modified to render them noninfectious Refrigerator stable—store between 2 and 8°C Purified protein matrix treated with...

This product is wheat germ agglutinin (WGA) labeled with horseradish peroxidase (HRP). WGA is a carbohydrate-binding lectin that has high affinity for sialic acid and N-acetylglucosamine.WGA conjugates can be used to stain glycoproteins that have these sugar moieties. WGA can be used as a gram stain...

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

ZeptoMetrix external controls have demonstrated performance on a variety of molecular assays. The product has been tested with Cepheid® GeneXpert® system and provides the expected results, however performance characteristics must be established by the end user. Formulated with purified,...

The Influenza Rapid Test Control Pack is intended for use with in vitro rapid tests for the determination of the presence or absence of Influenza A and B.

Streptavidin is a tetrameric protein purified from Streptomyces avidinii. It has wide use in numerous molecular biological protocols dues to its strong affinity for biotin. NWSHPQFEK (Strep II tag) is a nine amino acid peptide with high specificity and affinity towards streptavidin. GenScript THE...

Somatostatin receptors (SSTRs), a family of seven transmembrane (™) domain G-protein-coupled receptors having five distinct subtypes (termed SSTR1–5), are activated by somatostatin secreted from the nerve and endocrine cells. SSTRs are widely expressed in many tissues, frequently as multiple...

TNF is secreted by macrophages, monocytes, neutrophils, T-cells, NK-cells following their stimulation by bacterial LPS. Cells expressing CD4 secrete TNF-alpha while CD8 cells secrete little or no TNF-alpha. The synthesis of TNF-alpha is induced by many different stimuli including interferons, IL2,...

DiO is a carbocyanine membrane dye that has applications similar to those of DiI. However, DiO has green fluorescent emission and the lateral diffusion rate on the membranes is generally slower than that of DiI. DiO and DiI are often used together in dual color studies. Also see Neuro-DiO, which has...

The GenBuilder Cloning Kit enables seamless and one-step cloning of multiple DNA fragments into a linearized vector. The proprietary enzyme mix fuses together DNA fragments efficiently and precisely by recognizing 15-40 bp overlaps at the end of each fragment. The system allows cloning of DNA...

Single donor specimens collected during the course of infection progression.

Live-or-Dye™ Fixable Viability Staining Kits allow discrimination between live and dead cells by flow cytometry or microscopy. Live/dead stains are useful probes to include when analyzing cell surface protein expression by flow cytometry, because they allow intracellular fluorescence signal from...

Phalloidin conjugates are actin filament stains for fixed and permeabilized cells. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Far-red fluorescent CF®640R dye has...

MemBrite Fix 640/660 is a far-red fluorescent dye that covalently labels the surface of live cells. Unlike lipophilic membrane dyes, MemBrite is well-retained after fixation and permeabilization or methanol fixation.

EverBrite TrueBlack® with DAPI is a hardset antifade mounting medium with Biotium's unique lipofuscin quencher, for one-step mounting, nuclear counterstaining, and autofluorescence quenching of fluorescently stained samples. It cures over time to form a permanent seal between coverslip and sample.

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

Detection kits for Neisseria gonorrhoea Available in TaqMan format for analysis Neisseria gonorrhoeae is a Gram-negative coccus of the Neisseria genus. N. gonorrhoeae is usually seen in pairs infecting human cells. It has a circular DNA genome of approximately 1Mbp encoding over 2000 genes. N....

Adiponectin is a hormone mainly produced by adipocytes. Adiponectin forms a homotrimer and exists as higher order multimers in vivo . The receptors of Adiponectin are seven transmembrane G protein coupled receptors: Receptor 1 is expressed in skeletal muscle and Receptor 2 in liver. Adiponectin...

In vitro diagnostic external run controls for evaluating and monitoring qualitative molecular assays for the detection of Chlamydia trachomatis LGVII-434 nucleic acids Formulated with purified, intact organisms Organisms are chemically modified to render them noninfectious Refrigerator stable—store...

P2Y4 is a receptor that is activated by UTP specifically. Activation of P2Y4 results in increased inositol phosphate formation and mobilization of intracellular calcium. Although selective antagonists for P2Y4 are still lack, P2Y4 may play an important role in vascular diseases, and immunomodulatory...
