DELFIA® Anti-IgG Rabbit Antibody (Europium N1-chelate)

Catalog Number: (101680-202)
Supplier: Revvity Health Sciences
Description: Generic DELFIA® reagents are intended for use in dissociation-enhanced time-resolved fluorometric assays. All reagents have been labeled using the DELFIA® N1-chelate. They are suitable for highly sensitive end point measurements in separation based assays such as those for detection of protein-protein binding and cell adhesion as well as for immunoassays. DELFIA® (dissociation-enhanced lanthanide fluorescence immunoassay) is a time-resolved fluorescence (TRF) intensity technology. Assays are designed to detect the presence of a compound or biomolecule using lanthanide chelate labeled reagents, separating unbound reagent using wash steps. DELFIA assays are flexible, compatible with a variety of plate readers, and, as this is a wash-based technology, compatible with most sample types. The technology is based on fluorescence of lanthanide chelates (Europium, Samarium, and Terbium). The fluorescence decay time of these lanthanide chelate labels is much longer than traditional fluorophores, allowing efficient use of temporal resolution for reduction of autofluorescent background. The large Stokes’ shift (difference between excitation and emission wavelengths) and the narrow emission peaks contribute to increasing signal-to-noise ratio. Sensitivity is further increased because of the dissociation-enhancement principle: the lanthanide chelate is dissociated and a new highly fluorescent chelate is formed into a protective micellar solution. DELFIA lanthanide chelates require this dissociation/enhancement step for fluorescence (induced by addition of DELFIA Enhancement solution, DELFIA Inducer, and DELFIA Enhancer as appropriate to the particular lanthanide chelate).

DELFIA® Anti-Phosphothreonine Rabbit Polyclonal Antibody (Europium N1-chelate)

Catalog Number: (101674-484)
Supplier: Revvity Health Sciences
Description: The antibody is an affinity purified rabbit polyclonal IgG (supplied by New England Biolabs). Affinities for the various phosphothreonine peptides are as shown below. Affinities are expressed as signal-to-noise ratios measured using 10ng/well anti-phosphothreonine antibody followed by DELFIA® europium labelled anti-rabbit antibody for detection. Noise is the reactivity with the non-phosphopeptide. Generic DELFIA® reagents are intended for use in dissociation-enhanced time-resolved fluorometric assays.

Insulin-like Growth Factor 2 (Human) AlphaLISA Detection Kits, PerkinElmer

Supplier: Revvity Health Sciences
Description: Formats: 500 assay point kit allows you to run 500 wells in 96-well or 384-well format, using a 50 µl reaction volume (5 µl of sample). 5000 assay point kit allows you to run 5000 wells in 96-well or 384-well format, using a 50 µl reaction volume (5 µl of sample). Features: no-wash steps, no separation steps, ELISA alternative technology, sensitive detection, broad sample compatibility, small sample volume, results in less than 3 hours, half the time of an ELISA assay. Insulin-like Growth Factor 2 (IGF2) is 67 amino acids in length after being fully processed. Its actions are mediated by binding to specific cell surface receptors. The major role of IGF2 is as a growth promoting hormone during gestation. In general, the insulin-like growth factor pathway plays a major role in cancer cell proliferation, survival and resistance to anti-cancer therapies in many human malignancies. IGF2 could be potentially be an important serum biomarker for prognosis of certain cancers. AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated donor beads while another anti-analyte antibody is conjugated to AlphaLISA acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the donor beads causes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the acceptor beads, resulting in a sharp peak of light emission at 615 nm.

Features: No-wash steps, no separation steps ELISA alternative technology Sensitive detection Broad sample compatibility Small sample volume Results in less than 3 hours Half the time of an ELISA assay There are five classes of mammalian immunoglobulins: IgA, IgD, IgE, IgM, and IgG. IgG is the most abundant immunoglobulin and is equally distributed in blood and tissue. In mice, the IgG class is further divided into four subclasses: IgG, IgG2a/ IgG2c (strain specific), IgG2b, and IgG3. The general immunoglobulin structure is composed of four polypeptide chains, two heavy and two light chains linked together and to each other by disulfide bonds, creating a tetrameric quaternary structure. IgG is involved in response to a foreign antigen. The presence of IgG usually signifies a mature antibody response. IgG has a molecular weight of about 150 kDa, it can bind to many pathogens and also plays an important role in antibody-dependent cell-mediated cytotoxicity. Typically mouse serum and plasma samples contain about 7 to 10 mg/ml of IgG. The present kit permits detection of mouse IgG (i.e. analyte) in different sample matrices, including different cell culture media. AlphaLISA technology allows the detection of molecules of interest in a no-wash, highly sensitive, quantitative assay. In an AlphaLISA assay, a biotinylated anti-analyte antibody binds to the Streptavidin-coated Donor beads while another anti-analyte antibody is conjugated to AlphaLISA Acceptor beads.
