BactoView™ Dead 560/570 is a novel orange 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.

MemBrite Fix 543/560 is a orange 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.

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.

5-CR110-PEO₄ SE (full name: 5-Carboxyrhodamine 110-PEO₄-propionate, succinimidyl ester, single isomer) is an excellent green fluorescent rhodamine dye for labeling amines. The dye has better solubility than the parent dye 5-CR110 SE and its long PEG spacer should reduce any...

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

An analytical reference standard categorized as an intermediate in the phytocannabinoid biosynthetic pathway; a precursor in the synthesis of CBDV, CBGV, and CBV; intended for research and forensic applications

Mix-n-Stain™ Antibody Labeling Kits are a revolutionary antibody labeling technology that allows you to label your antibody with one of our superior CF® dyes in 30 minutes without a purification step. The labeling procedure tolerates many common buffer components and antibody stabilizers. CF® dyes...

PMA is a high affinity photoreactive DNA binding dye developed by Biotium for viability PCR. PMAxx™ is Biotium's new and improved viability PCR dye. The dyes are weakly fluorescent by themselves but become highly fluorescent upon binding to nucleic acids. Upon photolysis, the dye forms a stable...

Detection kits for Trichomonas vaginalis Available in TaqMan format for analysis Norgen’s Trichomonas vaginalis End-Point PCR Kit is designed for the detection of Trichomonas vaginalis specific DNA based on the use of end-point PCR technology. This kit is designed for research use only and not for...

MQAE (N-(Ethoxycarbonylmethyl)-6-methoxyquinolinium bromide) is an improved chloride indicator that has greater sensitivity to chloride (K_sv= 200M -1 ) than SPQ (K_sv=118 M -1 ) and higher fluorescence quantum yield. The ester group of MQAE may slowly hydrolyze inside cells,...

Evaluate the performance of nucleic acid tests for determination of the presence of Echovirus 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 0.09%...

EverBrite TrueBlack® is a hardset fluorescence antifade mounting medium with Biotium's unique lipofuscin quencher, for one-step mounting and autofluorescence quenching of fluorescently stained tissue sections. The medium cures over time to form a permanent hard seal between coverslip and specimen.

KE00097 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The Fetuin A ELISA kit is to be used to detect and quantify protein levels of endogenous Fetuin A. The assay recognizes human Fetuin A. An antibody specific for Fetuin A has been pre-coated onto the microwells....

Transforming Growth Factor-alpha (TGF-a) , also known as sarcoma growth factor, TGF-type I and ETGF, is a member of the EGF family of cytokines. It is expressed in monocytes, brain cells, keratinocytes and various tumor cells. TGF-a signals through EGFR and acts synergistically with TGF-beta to...

Oncostatin M (OSM) is a multifunctional cytokine, and belongs to Interleukin-6 (IL-6) subfamily, which also includes IL-11, leukemia inhibitory factor (LIF), ciliary neurotropic factor, cardiotrophin-1, and novel neurotropin-1. In vivo, OSM is secreted from activated T cells, monocytes, neutrophils,...

A Camelid VHH Antibody (also called single-domain antibody, sdAb or Nanobody by Ablynx) is a peptide chain of about 110 amino acids long, comprising one variable domain of a heavy-chain antibody. Like a whole antibody, it is able to bind selectively to a specific antigen. Single-domain antibodies...

Tetramethylrhodamine (TAMRA) cadaverine (full name: 5-(and-6-)-((N-(5-Aminopentyl)amino)carbonyl)tetramethylrhodamine) can be coupled to activated carboxy groups or sulfonyl chlorides.    &lamba;_Ex/&lamba;_Em (MeOH) = 544/571 nm   Dark purple solid soluble in DMSO...
