| Description | This lectin (MAL) is the leucoagglutinin or mitogenic isolectin form from Maackia seeds. This multimeric lectin dissociates into 38,000 and 40,000 molecular weight bands in SDS gels in the presence of reducing agents and is a single 75,000D band without reducing agents. It has an isoelectric point about pH 4.6 and has been reported to have a molecular weight of about 130,000 by gel filtration. This lectin binds glycoconjugates having galactosyl (b-1,4) N-acetylglucosamine structures. Maackia amurensis lectin I seems to tolerate substitution of N-acetyllactosamine with sialic acid at the 3 position of galactose. However, MAL I does not appear to bind this structure when substitution with sialic acid is on the 6 position of galactose. 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 Histochemistry. Other applications not tested. Recommended Dilution: Optimal dilutions to be determined by the researcher. Inhibiting Sugar: 200mM lactose Storage and Stability: Lyophilized powder may be stored at -20°C. Stable for 12 months at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Reconstituted product is stable for 6 months 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. | ||
