產(chǎn)品描述：

番茄凝集素（Tomato lectin, Lycopersicon Esculentum lectin (LEL)）,是一種非常穩(wěn)定的單亞基糖蛋白，約含有等量的蛋白和碳水化合物。據(jù)報(bào)道其糖類部分由85%半乳糖組成，在溶液中可能形成多聚體聚合物。番茄凝集素雖然和土豆凝集素、曼陀羅凝集素（DSL）和麥胚凝集素（WGA）有部分相同的特異性、但在許多多面呈現(xiàn)出du特之處。番茄凝集素LEL能夠很好地與血型糖蛋白（glycophorin）和tamm-Horsfall糖蛋白結(jié)合，能夠有效結(jié)合和標(biāo)記嚙齒類動(dòng)物的血管內(nèi)皮（vascularendothelium）

Overview

Tomato lectin (from Lycopersicon esculentum) is an effective marker of blood vessels and microglial cells in rodents. Conjugation of the lectin with a fluorophore facilitates fast, one-step detection and visualization using intravascular perfusion methods or direct application to tissue sections.

DyLight® 649 labeled tomato lectin 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 655 nm and the emission maximum is at 670 nm (far red).

More Information

Tomato lectin is a very stable single subunit glycoprotein containing about 50 percent arabinose and galactose and may form multimeric aggregates in solution. Tomato lectin, although sharing some specificities with potato lectin, Datura lectin, and wheat germ agglutinin, has been reported to be dissimilar in many respects. LEL binds well to glycophorin and Tamm-Horsfall glycoprotein and has been used effectively to label vascular endothelium in rodents.

DyLight® 649 conjugated tomato lectin emits in the far red and is an excellent second label in systems with green/yellow fluorescence such as GFP expressed in transgenic animals, or with fluorescein conjugates in standard double label studies. The tomato lectin complements our existing range of lectin reagents and should be a valuable tool in examining rodent tumor angiogenesis, tracing neovascular development in xenograft models and brain research.

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 preserved with sodium azide.
