Wisteria floribunda (WFA, Japanese Wisteria) (AP)

Purified Wisteria floribunda lectin (WFA), Alkaline Phosphatase conjugated.||Lectins are derived from the extracts of plants, animals, viruses and microorganisms and are known to agglutinate red blood cells. These agglutinins can select cell types according to blood group activities utilizing sugar-binding mechanisms. ||Lectins form precipitates with glycoconjugates and are useful for identifying or separating oligosaccharides with identical sugar compositions such as galactose, mannose or glucose.||Carbohydrate Specificity: N-Acetylgalactosamine||Inhibitory Carbohydrate: N-Acetylgalactosamine >> Lactose >> Galactose||Activity: 15-30ug/ml will agglutinate type A1 human erythrocytes. Less than 0.5ug/ml will agglutinate neuraminidase treated erythrocytes.||Storage and Stability: |May be stored at 4°C before opening. DO NOT FREEZE! Stable at 4°C as an undiluted liquid. Dilute only prior to immediate use. Stable for 6 months. 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.|Freezing alkaline phosphatase conjugates will result in a substantial loss of enzymatic activity.
