Product FAQs

The Lycopersicon esculentum (tomato) lectin has been widely reported as an effective blood vessel marker for in vivo vascular perfusion studies in rodent species. Investigators have primarily utilized one of the fluorophore conjugated tomato lectin formats to trace blood vasculature in normal and diseased animals via tail vein or intracardiac injection. However, the biotinylated format has also been used. It allows for flexibility in subsequent visualization by way of either fluorescence or enzyme-based methods. Published references are best source for procedural details. Examples of references where biotinylated tomato lectins have been applied via in vivo perfusion are featured below: Robertson, R.T., et al. (2014) Histochem. Cell Biol. 143(2) Thurston, G., et al. (1998) Am. J Pathol. 153(4):1099-1112

Technical Information

GSL I is a family of glycoproteins with molecular weights of approximately 114 kDa. There are two types of subunits, termed A and B, with slightly different molecular weights. These subunits combine to form tetrameric structures, resulting in five isolectins. The A -rich lectin preferentially agglutinates blood group A erythrocytes and thus appears to be specific for α-N-acetylgalactosamine residues, while the B -rich lectin preferentially agglutinates blood group B cells and is specific for α-galactose residues. Our GSL I is a mixture of the five isolectins. GSL I has been reported to bind several glycoproteins including laminin.

Technical Information

Tomato lectin is a very stable single subunit glycoprotein containing about 50 percent arabinose and galactose and may form multimeric aggregates in solution. Tomato lectin, although sharing some specificities with potato lectin, Datura lectin, and wheat germ agglutinin, has been reported to be dissimilar in many respects. LEL binds well to glycophorin and Tamm-Horsfall glycoprotein.

DyLight™ 649 conjugated tomato lectin emits in the far red and is an excellent second label in systems with green/yellow fluorescence such as GFP expressed in transgenic animals, or with fluorescein conjugates in standard double label studies. The tomato lectin complements our existing range of lectin reagents and should be a valuable tool in examining rodent tumor angiogenesis, tracing neovascular development in xenograft models and brain research.

Product FAQs

Virtually any tissue type and species are suitable for use with a Glysite Scout Glycan Screening Kit, Immunofluorescence, as glycans are ubiquitous in nature and in life. The kit has been validated on human and mouse tissue—including FFPE tissue, across a range of organs, including colon, lung, spleen, kidney, liver, pancreas, testes, heart, bladder, and uterus.

Each of the three Glysite Scout Glycan Screening Kits, Immunofluorescence contain the same lectins but with a different fluorescent streptavidin detection reagent, offering a choice of Dylight™ 488 (GSK-3000), Dylight™ 594 (GSK-2000), or Dylight™ 649 (GSK-1000). This allows users to choose the kit which best matches the capabilities of their fluorescent microscope and also provides flexibility for multiplexing with other fluorescent detection reagents they might already be using. 

VECTASHIELD Vibrance is an antifade medium for immunofluorescence applications with setting properties, which means the coverslip is immobilized after curing and does not require sealing. Additionally, slides can be stored at room temperature, enabling extended archiving time. VECTASHIELD PLUS does not have setting properties and remains molten, and slides must be stored at 2–8°C. Both VECTASHIELD Vibrance and VECTASHIELD PLUS have superior antifade/anti-photobleaching properties across the spectrum and are compatible with commonly used fluorophores. 

The need for an antigen retrieval step in a staining protocol depends on multiple variables, including the target glycan and its location in the specimen, the glycan-binder, the type of tissue, and the method and length of fixation. Investigators should run controls with and without antigen retrieval to determine if this step is needed for their specimen. 

Tissue components such as red blood cells, elastin, and collagen are strongly fluorescent, particularly in FFPE sections, making it difficult to discern between relevant signal and background. Formalin fixation tends to induce a significant amount of fluorescence to a specimen. The Vector TrueVIEW Autofluorescence Quenching Kit provides a dramatic reduction of autofluorescence, allowing a clear view of the desired signal, so it was utilized as needed on the specimens represented in the images. 

If co-labeling with a primary antibody, users should optimize each protocol separately to achieve maximum signal to noise ratios. Once this is complete, the two protocols can be combined, with the Glysite Scout Glycan Screening Kit protocol applied first, followed by the antibody staining protocol. Users should perform the proper controls to demonstrate that the reagents in each protocol are not cross–reacting with each other. 

The Carbo-Free Blocking Solution included in the Glysite Scout Glycan Screening Kit is virtually free of glycoproteins or other glycosylated molecules. This is critical since these kits detect glycans and would therefore bind to blocking reagents which contained glycosylated components. Users should not use other blocking solutions (e.g., milk derivatives, sera) as it may lead to high background. 

Each Glysite Scout Glycan Screening Kit contains enough reagents for approximately 50 tissue samples per lectin, or up to 400 samples if using one lectin per tissue sample (8 lectins x 50 tissue samples). 

The lectins were selected based upon their broad applicability and specificity to frequently cited glycan targets from literature sources, spanning fields of Cancer, Immunology, Metabolism, Inflammation, Virology, and Tumor Microenvironment, among others. They enable detection of all the major glycan motifs for the evaluation of glycan distribution in a target specimen. 

Technical Information

The lectins selected for the Glysite Scout Glycan Screening Kit, Immunofluorescence 649 were specifically chosen to provide detection of all of the major glycan motifs for the evaluation of glycan distribution in a target specimen. Follow our optimized protocol or view our how-to video to learn how you can rapidly explore glycan expression in your tissue section.

In addition to the glycan binders, the kit includes optimized immunofluorescence reagents for glycan detection, including blocking solutions, DyLight™ streptavidin, and VECTASHIELD Vibrance® Antifade Mounting Medium with DAPI.

Technical Information

The anti-mouse Ig antibodies are prepared by hyperimmunizing animals in a manner that produces high affinity antibodies. These are then purified by an affinity chromatography procedure designed to remove any low affinity antibodies which may be present. Cross-reactivities that are likely to interfere with specific labeling are removed by solid-phase adsorption techniques. The final product is then subjected to rigorous quality control assays including immunodiffusion, solid-phase enzyme immunoassays, gel electrophoresis and solid-phase binding assays. In preparing the labeled antibodies, great care is taken to ensure the maximum degree of labeling with no alteration in the specificity and affinity of the antibody. The labeled antibody then undergoes a further series of quality control assays, including immunohistochemical analysis.
DyLight™ fluorescent dyes are direct alternatives to traditional fluorophores such as fluorescein (FITC) and rhodamine. The excitation and emission spectra parallel that of other commercially available fluorescent reagents allowing for easy substitution into an existing protocol without requiring any further instrumentation or filter sets.
DyLight™ dyes offer a number of potential advantages including greater photostability and brighter fluorescence.  DyLight™ dyes are completely stable over a pH range of 4-9 making them compatible with many aqueous-based buffers and diluents. The DyLight™ dyes can be applied as single labels or in combination with other DyLight™ dyes and fluorophores as part of a multiple immunofluorescent antigen staining methodology.  The DyLight™ dyes currently offered are DyLight™ 488 (green), DyLight™ 549 (orange), DyLight™ 594 (red), and DyLight™ 649 (far red).
