Excellent Chemiluminescent Substrate (ECL)Detection Kit
中文名称:化学发光 (ECL)底物液
Price:
- 应用性: WB;ELISA
产品简介 | Elabscience®化学发光(ECL) 底物液是一款辣根过氧化物酶(HRP) 底物,可用于检测辣根过氧化物酶(HRP)标记的蛋白或核酸,用于蛋白质印迹或ELISA等分析蛋白含量,可兼容胶片和数字显影系统。 |
保存条件 | 2~8°C避光保存,保质期12个月 |
注意事项 | 1. 曝光背景高,可能是膜没洗干净、二抗或一抗浓度过高、封闭液不合适导致,请做适当调整。 2. A液和B液在吸取过程中必须要更换吸头,A液和B液相互污染后会导致其逐渐失效。 3. 如无信号,可能是目的蛋白表达弱,可适当延长曝光时间。 4. 荧光迅速淬灭,可能是目的条带荧光信号过强,导致HRP快速消耗ECL底物,建议降低二抗浓度。 5. NaN3或金属螯合剂会抑制HRP 活性,溶液中应避免使用。 6. 工作液需现配现用。 |

Q1:IHC在数据表上是什么意思?是冷冻切片吗?与IHC-F区别?
IHC是免疫组化实验,使用的切片一般包含有IHC-P(石蜡切片)和IHC-F(冰冻切片)两种。
Q2:IHC实验,想知道抗原修复条件是什么?是用EDTA还是枸橼酸钾?
修复条件一般为高温高压或者微波加热修复。 例如:抗原修复(高压法) :压力锅中加入足以淹没切片的 10 mmol/ml 的枸橼酸盐缓冲液(pH 6.0) (配制:将抗原修复液溶于相应体积 ddH2O中,混匀),加热至沸腾,切片置耐热塑料切片架上,放入锅中,盖好锅盖,扣上压力阀,继续加热,设置保压 4 min,时间到后打开放气阀放气,压力归零后开锅盖将内锅取出放置室温冷却,待溶液冷却至室温后取出切片(约30 min)。 抗原修复(微波法) :烧杯中加入足以淹没切片的 10 mmol/ml 的枸橼酸盐缓冲液(pH 6.0) (配制:将抗原修复液溶于相应体积 ddH2O中,混匀),加热至沸腾,切片置耐热塑料切片架上,放入烧杯中,中小火加热30min后取出,放置室温冷却,待溶液冷却至室温后取出切片(约30 min)。 IHC修复液的选择建议参考抗体使用说明书,或者参考以下方案:人体样本,优先推荐使用pH9.0的EDTA修复液(临床样本);大/小鼠样本,优先推荐使用pH6.0的枸橼酸修复液(科研样本)。
