You searched for: Protein Linking and Labeling Systems

Protein linking and labeling systems provide a convenient means for attaching fluorescent labels or biotins to antibodies and larger proteins. These kits are ideal for use with multiple applications, including flow cytometry, fluorescent microscopy, immunohistochemistry, primary detection, ELISAs, immunocytochemistry, and FISH. These systems are available with a variety of dye colors, biotin, fluorescent agents, and all the components needed to perform multiple conjugations and purifications. Protein labeling follows a simple protocol of reaction, separation, and then use.

Amersham CyDye DIGE fluors

Supplier: Cytiva

CyDye™ DIGE fluors are available as minimal and saturation labeling dyes. The minimal dyes are intended for general 2-D application use where sufficient amounts of sample are available. The saturation dyes from the Scarce Sample Labeling Kit are designed to be used for applications where only small amounts of sample are available, for example in Laser Capture Microdissection.

Translation labelling system, GreenLys in vitro translation labelling system, FluoroTect™

Supplier: Promega

FluoroTect™ GreenLys in vitro Translation Labelling System enables fluorescent labelling and detection of in vitro synthesised proteins, based on a lysine-charged tRNA labelled with the fluorophore BODIPY®-FL at the ε position. Fluorescent lysine residues are incorporated into synthesised proteins during in vitro translation reactions, eliminating the need for radioactivity.

AP fluorescent substrate kit, AttoPhos®

Supplier: Promega

AttoPhos® AP Fluorescent Substrate System, utilising a highly sensitive fluorescent alkaline phosphatase (AP) substrate, maintains a low fluorescence signal until enzymatically acted upon, yielding detection of AP to as little as 0,1 attomole.

Ligand building blocks, HaloTag®

Supplier: Promega

Ligand building blocks can carry a variety of functionalities, including fluorescent labels, affinity tags and attachments to a solid phase. The covalent bond forms rapidly under general physiological conditions, is highly specific and essentially irreversible. The HaloTag® Ligand Building Blocks allow researchers to apply the chloroalkane group that HaloTag® protein reacts with to any compound or surface with a compatible chemical group, creating endless possible applications.

In Vivo Renilla Luciferase substrate, ViviRen™

Supplier: Promega

ViviRen™ in vivo Renilla luciferase substrate is a uniquely engineered coelenterazine-based compound with protected oxidation sites. These modifications are designed to minimise substrate degradation and autoluminescence. ViviRen™ Substrate is reported to demonstrate brighter output compared to the native coelenterazine substrate when used in an in vivo imaging application in a mouse model. High-quality substrate eliminates potential interference in assays due to the presence of endotoxins.

Fluorescent ligands, HaloTag®

Supplier: Promega

HaloTag® fluorescent ligands form covalent bonds rapidly under general physiological conditions. The bonds are highly specific and essentially irreversible. HaloTag® fluorescent ligands enable the addition of the chloroalkane group, with which HaloTag® protein reacts, to any compound or surface with a compatible chemical group.
