SpectraSplit® 7

SpectraSplit® 7 are patented filter sets that empower fluorescence microscopes with seven color channels.  The channels are distributed over four filter sets and specifically separate the most commonly used fluorochromes in immunofluorescence (see table below). Hence, you can immunostain tissues with up to seven fluorochromes and still visualize each fluorochrome in the sample with SpectraSplit® 7 without bleedthrough. No additional software and no computational spectral unmixing are required.

SpectraSplit® 7 can easily be installed in both standard and scanning fluorescence microscopes, and can be run with different popular light sources. See the description below for more information.

Cat no. 7001991-1

Description

The SpectraSplit® 7 filter sets are highly efficient in separating the emission signals of seven different fluorochrome classes, with spillover between channels being less than 0.5%. As a result, high-contrast images are generated without the need for spectral unmixing or any other bleed-through corrections.

SpectraSplit® 7 immediately empowers your microscope with seven independent color channels that each generates crystal clear images. Importantly, you do not need to be a fluorochrome expert or microscope guru to produce 7-color images.

Fluorochromes
SpectraSplit® 7 is fully compatible with commonly used fluorochromes, such as AlexaFluor® dyes, as well as the classic FITC/Cy3/Cy5/Cy7 dyes and many of the OpalTM dyes.

StreptaClick® Color

585 € – 1159 €
StreptaClick® Color is a modified streptavidin that labels antibodies with fluorochromes, mimicking directly conjugated antibodies as we have removed the issue of antibody aggregation through monovalent binding. StreptaClick® Color provides a rapid, robust, and flexible method for attaching fluorochromes to biotinylated antibodies. Once labeled with StreptaClick®, the antibody is stable and can be used in the same manner as antibodies that are directly conjugated with fluorochromes. The labeling reaction is highly efficient and can be carried out at any volume, concentration, or buffer.
  • The StreptaClick® Color 2-plex Kit contains: StreptaClick® Color 488 and StreptaClick® Color 647. Suitable for multiplex immunohistochemistry (IHC) and Flow Cytometry. (Cat. no. 50021-1)

StreptaClick® Precision

400 € – 3694 €
StreptaClick® Precision is a modified streptavidin designed for precise stoichiometric 1:1 conjugations. Currently, StreptaClick® Precision is available with exactly one azide or exactly one DBCO (dibenzylcyclooctyne). StreptaClick® Precision also features a unique cis-divalent design for enhanced monovalent binding to biotinylated proteins. In addition, the conjugation site and the biotin binding region are on opposite sides of StreptaClick® Precision, minimizing the risk of conjugates interfering with biotin binding. This design makes StreptaClick® Precision ideal for attaching bulky molecules without sterically hindering biotin binding and without causing aggregation when mixed with biotinylated antibodies in solution. StreptaClick® Precision is currently available with a single azide or DBCO group for either copper(I)-catalyzed azide-alkyne cycloaddition (CuAAC) or copper-free strain-promoted azide-alkyne cycloaddition (SPAAC) click chemistry. For oligonucleotides, we strongly recommend SPAAC click chemistry (DBCO/azide). Pre-conjugated StreptaClick® Precision products are also available. These include StreptaClick® Precision pre-conjugated with a single 14mer DNA oligonucleotide or a single bright fluorochrome (488 nm or 647 nm). Order or request further information
