Griffonia simplicifolia GS II (Bandeiraea simplicifolia) (FITC)

This lectin is a tetrameric glycoprotein composed of four subunits of nearly identical size. Each 30,000D subunit has a binding site for alpha- or beta-linked N-acetylglucosamine residues. Unlike other N-acetylglucosamine specific lectins, increasing the number of N-acetylglucosamine residues beyond two does not improve affinity. GSL II has been reported to be unique in its ability to recognize exclusively alpha- or beta-linked N-acetylglucosamine residues on the nonreducing terminal of oligosaccharides. Fluorescein labeled Griffonia (Bandeiraea) Simplicifolia Lectin II is produced by using the highest quality fluorescein isothiocyanate, our affinity-purified lectin, and special conjugation procedures. Fluorescein labeled Griffonia (Bandeiraea) Simplicifolia Lectin II has an appropriate number of fluorochromes bound which provide the maximum fluorescence and optimum staining characteristics for this particular lectin. This lectin is supplied essentially free of unconjugated fluorochromes and inactive lectin. Accompanying each fluorescent lectin is an analysis data sheet summarizing the results of our quality control tests and providing pertinent information on the product. All of these reagents are supplied as solutions perserved with sodium azide.

Suitable for use in FLISA. Other applications not tested.

Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer.
Caution: FITC conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
