The Lightning-Link™ kit allows antibody conjugates to be set up in seconds, simply by adding a solution of the protein to be labeled to a proprietary lyophilised mixture containing Alkaline Phosphatase (AP). By circumventing the desalting or dialysis steps that commonly interrupt traditional protein conjugation procedures, Lightning-Link™ technology can be used to label small quantities of protein with 100% recovery and without excessive dilution of the conjugate!

Upon dissolution of Lightning-Link™ mixture with a solution of the antibody (or other biomolecule to be labeled) proprietary chemicals in the mixture become activated. This results in the directional coupling of the antibody to the enzyme label in a gentle and controlled process at near-neutral pH. The hands-on time for the entire procedure is typically 20-30 seconds. Lightning-Link™ makes it possible to label primary antibodies and other proteins with ease, and eliminates the need for secondary reagents in immunoassay procedures such as Western blotting, ELISA and immunocytochemistry.

Alkaline phosphatase (AP) is a hydrolyase enzyme that is frequently conjugated to antibodies for use in immunoassays. AP has a lower catalytic rate than HRP, but has greater stability and maintains linear reaction kinetics for much longer. PNPP is a popular colorimetric substrate for AP; the product of the reaction, p-nitrophenol, can be read at 405nM. Fluorogenic substrates (e.g. 4-methylumbelliferyl phosphate; MUP) may also be employed.

Please note as well as AP, we currently have over 40 available labels including enzymes, fluorescent proteins and dyes that span a variety of applications (WB, IH, FACS, ELISA, and FRET), colours, and emission ranges

Lightning-Link™ Atto 610 kit

Innova Biosciences Ltd.

Say goodbye to secondary antibodies – Go direct using the World’s Easiest DIY Antibody Labeling Kit - Lightning-Link™! • Eliminates need for secondary antibodies • Reduces the number of wash steps • Ideal for multi-protein analysis – with over 40 available labels • Very easy to use • 100% antibody recovery Lightning-Link™ kits The DIY Lightning-Link™ kit allows you to label an antibody with minimal hands-on time - less than 30 seconds. Simply add your antibody solution to a tube of Lightning-Link™ mix and the label becomes covalently attached to your antibody in a gentle controlled process. Lightning-Link is the easiest and quickest method available for antibody conjugation.Go ‘direct’ Direct antibodies labelling greatly simplifies immunodetection techniques. Without the problems of crossover and/or non-specific binding from secondary reagents it is far easier to obtain high quality, pioneering results in techniques such as flow cytometry, ELISA, Western blotting and immunohistochemistry. A reduction in the number of incubation and wash steps also saves you time and money. The antibody conjugate: Atto610 is part of the new generation of fluorescent labels for the red spectral region. The dye presents high fluorescence emission at 640nm when excited at 575nm (extinction coefficient 1.5 x105 cm-1M-1) and high quantum yield. Atto610 can be used as a substitute dye for DY-610, BODIPY 630/650 and LightCycler Red 640 and Carboxynapthofluorescein.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Western BlottingWestern blotting equipment is used to transfer and identify specific proteins within a sample, reveal protein modifications, as well as give a semi-quantitative estimation of their concentration. Western blotting equipment includes all apparatus necessary to transfer proteins from gel to membrane and subsequent processing steps. Protein transfer can be performed by electroblotting with wet, semi-dry and dry transfer systems onto nitrocellulose and PVDF membranes. Blocking, washing and labeling of membranes follows, involving buffers, blocking reagents, blotting / incubation trays, labeling reagents, immunoblotting assays, antibodies and conjugates. Automated equipment for these steps is available to accelerate your lab workflow. Finally, detection and imaging of proteins can be conducted using gel documentation and imaging systems. Find the best western blotting equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.ELISAEnzyme-linked immunosorbent assays (ELISA), also known as enzyme immunoassays (EIA), are used for the detection and quantification of proteins, peptides and antibodies in a sample. ELISA often comes in kit format, with pre-selected antibody pairs to detect specific proteins or biomarkers of diseases such as diabetes and obesity, or cardiovascular and neurological disorders. Detection is made possible with chemiluminescent, fluorescent or colorimetric substrates and detection instruments such as microplate / ELISA readers. Other kits available include: Enzyme-linked immunospot (ELISPOT) assays for the quantification of protein-producing cells and chemiluminescent immunoassays (CLIA) kits. Find the best ELISA kits and products in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.ProteomicsProteomics is the systemic bioinformatics study of proteins and amino acids, including their structure, size, function and identification. Tools used in proteomics include chromatography, blotting and gels, protein arrays, mass spectrometry and ELISA and associated analysis software. Analyzers and proteomic systems should be sensitive, high resolution, fast and may be automated for high-throughput.Flow Cytometry / Cell CountingFlow cytometers are used to count, sort and examine multiple characteristics of cells. Other cell analysis equipment includes image cytometers, cell counters, fluorescence-activated cell sorters (FACS), magnetic-activated cell sorters (MACS), and a range of flow cytometry assay kits. Flow cytometers can reveal information on cell viability, cell proliferation, apoptosis and cell cycle progression, as well as identify cell populations and intracellular or cell-surface molecules. Additionally, some flow cytometers, known as FACS, have an additional sorting function after analysis. Cell counters and image cytometers count live and dead cell populations and can also conduct cell proliferation assays. Find the best flow cytometers, cell counters and cell sorters in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.ImmunologyImmunological techniques measure and characterize immune responses. Immunology kits and analysis systems often use techniques such as ELISA, radioimmunoassay (RIA) and immunodiffusion assays, Immunohistochemistry, and flow cytometry. Immunologists use equipment such as flow Cytometers, plate readers, plate washers and fluorescent microscopes.Cellular PathologyCellular Pathology deals with the microscopic analysis of tissue samples and cells. Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.Point-of-CarePoint-of-Care Testing (POCT) or Near Patient Testing (NPT) products are available for urine, blood and other clinical chemistry analyses. POCT includes: blood glucose testing, blood gas and electrolytes analysis, rapid coagulation testing (PT / INR), rapid cardiac markers diagnostics, drugs of abuse screening, urine strips testing, pregnancy testing, fecal occult blood analysis, food pathogens screening, hemoglobin diagnostics, infectious disease testing and cholesterol screening.BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :
