MemBrite Fix-ST 681/698 is a far-red/NIR fluorescent dye that covalently labels the surface of live cells. MemBrite Fix-ST dyes are well-retained after fixation and permeabilization, and are compatible with STORM super-resolution imaging.

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

•Perfect box for every blot •Reduce antibody usage •Hinged Lid minimizes evaporation •For halves, wholes, strips, or minisNo matter what size your Western blot is, there's a box that fits it perfectly. With boxes that are correctly matched to common blot sizes, you can fit more blots on...

KE00288 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The Human IL-1R2 ELISA kit is to be used to detect and quantify protein levels of endogenous IL-1R2. The assay recognizes human IL-1R2. An antibody specific for IL-1R2 has been pre-coated onto the microwells. The...

The motilin receptor (MTLR) represents a clinically useful pharmacological target, as agonists binding to the MTLR have gastroprokinetic properties. Motilin is a 22 amino acid peptide that potently stimulates gastrointestinal contractility. The biological effects of motilin are mediated by a...

Single donor specimens collected during the course of infection progression.

Evaluate the performance of nucleic acid tests for determination of the presence of targeted bacterial 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...

This gene encodes a receptor that binds the Fc region of monomeric immunoglobulin G. The encoded protein transfers immunoglobulin G antibodies from mother to fetus across the placenta. This protein also binds immunoglobulin G to protect the antibody from degradation.

KE10076 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The mouse CX3CL1 ELISA kit is to be used to detect and quantify protein levels of endogenous mouse CX3CL1. The assay recognizes mouse CX3CL1. An antibody specific for mouse CX3CL1 has been pre-coated onto the...

KE00110 is a solid phase sandwich Enzyme Linked-Immuno-Sorbent Assay (Sandwich ELISA). The Clusterin ELISA kit is to be used to detect and quantify protein levels of endogenous Clusterin. The assay recognizes human Clusterin. An antibody specific for Clusterin has been pre-coated onto the...

X-gal (5-Bromo-4-chloro-3-indolyl-β-galactopyranoside) is the most widely used chromogenic substrate for β-galactosidase. Enzyme hydrolysis of the substrate yields a dark blue colored precipitate (maximum absorbance 615 nm). White solid soluble in DMSO Store desiccated at -20°C and protect...

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

MitoView™ 405 is a blue fluorescent mitochondrial dye for live cells. It has excitation/emission at 398/440 nm for detection in the DAPI or Pacific Blue® channels. It is a replacement for our original MitoView™ Blue, with improved photostability.

Interleukin-2 (IL-2) is a Oglycosylated, four a-helix bundle cytokine that has potent stimulatory activity for antigen-activated T cells. It is expressed by CD4+ and CD8+ T cells, ?d T cells, B cells, dendritic cells, and eosinophils. IL-2/IL-2R signaling is required for T-cell proliferation and...

Evaluate the performance of nucleic acid tests for determination of the presence of GI bacterial, fungal, and viral nucleic acids Formulated with purified, intact organisms Organisms are chemically modified to render them noninfectious Refrigerator stable—store between 2 and 8°C Purified...

MIP-1 alpha/CCL3, also known as LD78 alpha, is an inflammatory chemokine. MIP-1a belongs to the CCL chemokine family, and shares 68% homology with MIP-1ß. The mature form of MIP-1a contains 69 amino acids, exists as dimers in solution, and tends to undergo reversible aggregation. The receptors of...

Chicken IgY is the designation for the IgG-like molecule found in avian species. The IMMUNOtek Chicken IgY (IgG) ELISA is a rapid, easy to use enzyme linked immunosorbent assay (ELISA) designed for the measurement of chicken IgY in chicken serum, egg yolk or white, plasma, saliva, mucosa, cell...

Apoptosis and necrosis are two major processes by which cells die. Apoptosis is an active, genetically regulated disassembly of the cell from within. During apoptosis, phosphatidylserine (PS) is translocated from the inner to the outer surface of the cell for phagocytic cell recognition. The human...

DMAO is a membrane-permeable DNA dye, excellent for staining live bacteria. DMAO preferentially binds to dsDNA with green fluorescence (excitation/emission (DNA bound) = 503/530 nm). Unlike the SYBR dyes, DMAO is extremely stable and can be routinely handled and stored at room temperature without...

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,...

Human IL-31 is a T-cell derived cytokine that shares several structural and functional characteristics with IL-6, Oncostatin M, LIF, and Cardiotrophin-1. It signals through a receptor complex comprised of GPL (GP130-like, IL-31RA) and OSMR (Oncostatin M receptor). GPL/OSMR signaling is a strong...

CF® Dye Amines can be used to conjugate CF® dyes to carboxylic acids groups in biological molecules. Carboxylic acids can be activated using water soluble carbodiimides to react with amine-functionalized dyes to form a stable amide bond. CF® dyes are Biotium's line of next-generation fluorescent...

Epidermal Growth Factor (EGF) is a potent growth factor that stimulates the proliferation of various epidermal and epithelial cells.
