NorthernLights™ Fluorescent Secondary Antibodies & Streptavidin Conjugates
NorthernLights™ fluorescent secondary antibodies and streptavidin conjugates are bright and resistant to photobleaching. We are currently offering secondary antibodies recognizing mouse, rat, goat, sheep, and rabbit IgG as well as chicken IgY. These reagents are available with three distinct excitation and emission maxima, making them ideal for multi-color fluorescence microscopy (Figure 1).... More Info
Technical Note: Using NorthernLights Fluorescent Secondary Antibodies for Neuronal Tracing
Immunofluorescence histochemistry is a powerful tool frequently used in neuroscience for qualitative and quantitative morphological and anatomical studies. Because samples are subjected to prolonged examination under conventional fluorescence microscopes and multiple laser-scanning confocal microscopes, it is critical for fluorescent tags to have a low susceptibility to photobleaching....

Targeted Gene Transfer with Fluorokines
An inherent difficulty in the field of gene therapy is the delivery of the gene of interest to a specific target cell population. The ideal system should be both efficient and accurate.1 The use of retroviral vectors has proved both inefficient and non-specific in its quest to deliver genes to targets such as hematopoietic progenitor cell lines.2 A more efficient gene transfer system has been...

Use of Proteome Profiler Arrays with LI-COR Detection
R&D Systems’ Proteome Profiler arrays are rapid, sensitive, and economical multiplex arrays for the simultaneous detection of many proteins in a single sample. Originally developed for chemiluminescent detection, many Proteome Profiler arrays are amenable to near-infrared (NIR) fluorescence detection using the LI-COR Odyssey® Infrared Imaging System. To achieve this adaptation, the... More Info

Detection & Visualization of Antibody Binding
Following incubation with the primary antibody, antibody binding is visualized using an appropriate detection system. The method of detection can be direct or indirect, and may generate a fluorescent or chromogenic signal. Direct detection involves the use of primary antibodies that are directly conjugated to a label. Indirect detection methods utilize a labeled secondary antibody raised against... More Info
