| Description | This lectin is a 150kD tetrameric glycoprotein consisting of four disulfide-linked chains, two of about 36kD and two of about 38kD. Sambucus nigra lectin binds preferentially to sialic acid attached to terminal galactose in (a-2,6), and to a lesser degree, (a-2,3), linkage. Binding is also inhibited to some extent by lactose or galactose. This lectin does not appear to bind sialic acid linked to N-acetylgalacto-samine. SNA has been reported to inhibit cell-free protein synthesis. This biotinylated lectin conjugate is prepared from affinity-purified lectin and is optimally labeled with biotin. Essentially free of inactive lectin conjugate and containing no free biotin, this biotinylated lectin provides an ideal intermediate for examining glycoconjugates using the Biotin-Avidin System. First the biotin-labeled lectin is added, followed by an ABC Reagent, Avidin D conjugate, or streptavidin derivative. Another possible application is in the isolation of lymphokines and other products of mitogenic stimulation. Applications: Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilutions: Optimal dilutions to be determined by the researcher. Elution: 500mM lactose in buffered saline followed by 500mM lactose in acetic acid Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months after receipt at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer. | ||
