产品介绍
用适当的过氧化物酶底物检测含有α-D-甘露糖、α-D-葡萄糖的糖蛋白通用Western Blot实验方法:糖蛋白样品规格:500ng凝集素浓度:0.1ug/ml每条泳道上样500 ng糖蛋白样品进行4-20% Bis-Tris SDS page凝胶转膜至PVDF膜上用于RIPA缓冲液(R0278 Sigma)在室温对膜进行封闭1小时在室温用RIPA缓冲液以0.1 ug/ml孵育HRP凝集素2小时用25ml RIPA缓冲液洗膜 5 x 5分钟用化学发光底物(CPS1-120)进行检测 Detects glycoproteins containing α-D-mannose, α-D-glucose when used with appropriate peroxidase substrate General Western Blot Protocol: Glycoprotein sample size: 500ng Lectin Concentration: 0.1ug/ml Load samples at 500 ng of glycoprotein per lane Run 4-20% Bis-Tris SDS page gel Transfer gel to a PVDF membrane Block membrane for 1 hr at RT with RIPA buffer (R0278 Sigma) Incubate HRP lectin at 0.1ug/ml with RIPA buffer for 2 hours at RT Wash membrane 5 x 5 minutes with 25ml RIPA buffer Detect using chemiluminescent substrate (CPS1-120)
生化机理
刀豆素 A 无血型特异性,但对末端 α-D-甘露糖基和 α-D-葡糖基残基具有亲和力。需要 Ca 2+ 和 Mn 2+ 离子存在才能显示活性。刀豆素 A 在 pH 6.5 或更低的条件下解离为二聚体。pH 在 5.8 至 7.0 之间时,刀豆素 A 以四聚体形式存在;pH 高于 7.0 时,形成更高的聚合体。根据聚合程度不同,刀豆素 A 可能显示出具有促有丝分裂的活性。琥珀酰化可以生成一种能够在 pH 高于 5.6 时仍保持二聚体形式的活性二聚体。
