Vector Labs 公司是世界著名的生物學檢測試劑公司,七十年代其在全球首推的生物素-親和素系統(tǒng)引領了生物學檢測方法的重大革命,該系統(tǒng)被普遍視為目前最靈敏、最可靠與最有效的染色系統(tǒng),并被廣泛應用于免疫組織化學、免疫電鏡、原位雜交與凝集素化學中。該系統(tǒng)仍在不斷地發(fā)展,以滿足廣大研究人員的各種不同要求。Vector 公司還是世界上凝集素產(chǎn)品的主要供應商,并提供大量的新產(chǎn)品,如酶底物、神經(jīng)元示蹤劑及蛋白質、糖類與核酸的標記、分離與檢測試劑。
Datura Stramonium Lectin (DSL), Fluorescein
Description
The carbohydrate binding site recognizes (β-1,4) linked?N-acetylglucosamine oligomers, preferring chitobiose or chitotriose over a single?N-acetylglucosamine residue. This lectin binds well in the acidic pH range but its affinity decreases above pH 8.0.
DSL also binds well to?N-acetyllactosamine and oligomers containing repeating?N-acetyllactosamine sequences. A branched pentasaccharide including two N-acetyllactosamine disaccharides linked to mannose (β-1,6) and (β-1,2) was reported to be the most potent inhibitor of agglutination.?
Fluorescein labeled DSL has an appropriate number of fluorochromes bound to provide the optimum staining characteristics for this lectin. This conjugate is supplied essentially free of unconjugated fluorochromes. The excitation maximum is at 495 nm and the emission maximum is at 515 nm.
