产品描述
番茄凝集素（Tomato lectin，Lycopersicon Esculentum Lectin（LEL）），是一种非常稳定的单亚基糖蛋白，约含有等量的蛋白质和碳水化合物。据报道其糖类部分由85%阿拉伯糖和15%半乳糖组成，在溶液中可能形成多聚体聚合物。番茄凝集素虽然和土豆凝集素、曼陀罗凝集素（DSL）和麦胚凝集素（WGA）有部分相同的特异性，但在许多多面呈现出*之处。番茄凝集素LEL能够很好地与血型糖蛋白（glycophorin）和Tamm-Horsfall糖蛋白结合，能够有效结合和标记啮齿类动物的血管内皮（vascular endothelium）。
本品为生物.*素化的番茄凝集素（来源于Lycopersicon esculentum），是一种理想的中间体检测糖偶联物，通过生物.*素-亲和素/链霉亲和素系统。首先加入生物.*素化凝集素，随后使用VECTASTAIN® ABC，Avidin D conjugate或streptavidin derivative。
产品特征
Synonyms | Biotin-LEL; Biotin-LEA; |
Sugar Specificity | [GlcNAc]1-3, N-Acetylglucosamine |
Applications | Immunohistochemistry / Immunocytochemistry, Elispot, ELISAs, Glycobiology, Immunofluorescence, Blotting Applications |
Working Concentration | For most applications, we recommend a freshly prepared working solution of 5-20 µg/ml in the above buffer. |
State | Powder |
Reconstitution | Reconstitute by adding 0.5 ml of water. The resulting solution will have the following composition: 10 mM HEPES, pH 7.5, 0.15 M NaCl, 0.08% sodium azide, 0.1 mM Ca++. |
Inhibiting/Eluting Sugar | Chitin Hydrolysate |
Storage | Refrigerate; for long term storage, aliquots may be stored frozen. |
使用方法（Histochemistry）【更多请点击此处下载Lectin Immunohistochemistry, Elisa, Western Blots Guidelines】
1a. Staining procedure for paraffin sections: Deparaffinize and hydrate tissue sections through xylenes or other clearing agents and graded alcohol series and rinse for 5 minutes in tap water. If required, retrieve antigens using the Antigen Unmasking Solution (H-3300 or H-3301).
1b. Staining procedure for frozen sections: Air dry sections. Immediay before staining, fix sections with acetone. Transfer slices to buffer. If endogenous enzyme activities are present, inactivate using appropriate methods.
2. Perform Streptavidin/Biotin blocking if required following kit instructions (SP-2002). Avidin in the Avidin/Biotin Blocking Kit (SP-2001) is a glycoprotein containing terminal mannose residues. Use of the Avidin/Biotin Blocking Kit is not recommended especially when using mannose-specific lectins.
3. Block non-specific binding by incubating section with Carbo-Free™ Blocking Solution (SP-5040) for 30 minutes at room temperature. Blot excess blocking solution from the sections.
4. Apply biotinylated lectin at approximay 2-20 µg/ml in PBS (10 mM sodium phosphate, 150 mM NaCl, pH 7.4) to the sections and incubate for 30 minutes at room temperature. Wash with TPBS (PBS + 0.05% Tween™ 20).
5. Prepare VECTASTAIN® ® ABC (peroxidase, PK-6100) or VECTASTAIN® ABC-AP (alkaline phosphatase, AK-5000) reagents according to the kit instructions. Apply to the sections and incubate for 30 minutes at room temperature. Wash with TPBS.
6. Apply an appropriate precipitating substrate for the enzyme system used in step 4. For peroxidase, ImmPACT™ DAB (SK-4105) is recommended; for alkaline phosphatase, ImmPACT™ Vector® Red (SK-5105). Rinse in tap water.
7. Counterstain (optional), clear and mount. For galactose or GalNAc-specific lectins we recommend that sections be mounted in VECTASHIELD® HardFSet™ Mounting Medium (H-1400) or VECTASHIELD® HardFSet™ Mounting Medium with DAPI (H-1500).
