通用注释

亚单元:

Homotetramer (By similarity). Interaction with tetrameric potassium channel alpha subunits gives rise to a heterooctamer (Probable). Identified in potassium channel complexes containing KCNA1, KCNA2, KCNA4, KCNA5, KCNA6, KCNAB1 and KCNAB2 (By similarity). Interacts with KCNA1 (By similarity). Interacts with the dimer formed by GNB1 and GNG2; this enhances KCNA1 binding (By similarity). Interacts with KCNA4 (PubMed:9763623). Interacts with KCNA5 (PubMed:12130714). Interacts with KCNB2 (By similarity). Interacts with SQSTM1 (By similarity). Part of a complex containing KCNA1, KCNA4 and LGI1; interaction with LGI1 inhibits down-regulation of KCNA1 channel activity.

功能:

Cytoplasmic potassium channel subunit that modulates the characteristics of the channel-forming alpha-subunits (PubMed:7499366, PubMed:7603988, PubMed:17156368,PubMed:17540341, PubMed:19713757). Modulates action potentials via its effect on the pore-forming alpha subunits (By similarity). Promotes expression of the pore-forming alpha subunits at the cell membrane, and thereby increases channel activity (By similarity). Mediates closure of delayed rectifier potassium channels by physically obstructing the pore via its N-terminal domain and increases the speed of channel closure for other family members (PubMed:9763623). Promotes the closure of KCNA1, KCNA2 and KCNA5 channels (PubMed:7499366, PubMed:7890032, PubMed:7603988, PubMed:7649300, PubMed:8938711, PubMed:12077175, PubMed:12130714, PubMed:15361858, PubMed:17540341, PubMed:19713757). Accelerates KCNA4 channel closure (PubMed:7890032, PubMed:7649300, PubMed:7890764, PubMed:9763623). Accelerates the closure of heteromeric channels formed by KCNA1 and KCNA4 (PubMed:17156368). Accelerates the closure of heteromeric channels formed by KCNA2, KCNA5 and KCNA6 (By similarity). Isoform KvB1.2 has no effect on KCNA1, KCNA2 or KCNB1 (PubMed:7890032, PubMed:7890764). Enhances KCNB1 and KCNB2 channel activity (By similarity). Binds NADPH; this is required for efficient down-regulation of potassium channel activity (PubMed:17540341). Has NADPH-dependent aldoketoreductase activity (By similarity). Oxidation of the bound NADPH strongly decreases N-type inactivation of potassium channel activity.

人KCNAB1ELISA试剂盒可以做多少个样本？

人KCNAB1ELISA试剂盒分为2种规格，96孔和48孔。96孔的试剂盒，标曲和样本都做复孔的话，可以检测40个样本。96孔的试剂盒，标曲和样本都不做复孔的话，可以检测88个样本。

人KCNAB1ELISA试剂盒是放在-20℃冰箱保存吗？

EIAab的人KCNAB1ELISA试剂盒，洗涤液、底物、终止液保存于4℃，其余试剂-20℃冰箱保存。

人KCNAB1ELISA试剂盒原理？

双抗体夹心法：用纯化的抗体包被微孔板，制成固相抗体，往包被有固相抗体的微孔中依次加入标准品或受检样本、生物素化抗体、HRP标记的亲和素，经过彻底洗涤后用底物TMB显色。用酶标仪在450nm波长下测定吸光度(OD值）,计算样本浓度。
竞争法：用纯化的抗体包被微孔板，制成固相抗体，往包被有固相抗体的微孔中依次加入标准品或受检样本和生物素标记的目标分析物，受检标本中抗原与生物素标记抗原竞争结合有限的抗体。再加入HRP标记的亲和素，经过彻底洗涤后用底物TMB显色。用酶标仪在450nm波长下测定吸光度(OD值）,计算样本浓度。

[5].

人KCNAB1ELISA试剂盒中需要使用的样品量是多少？

夹心法100μL/孔，竞争法50μL/孔。如样本浓度过高时，应对样本进行稀释，以使稀释后的样本符合试剂盒的检测范围，计算时再乘以相应的稀释倍数。

[6].

如何分析人KCNAB1ELISA试剂盒数据？

建议标准曲线，并计算样本浓度。对于elisa的曲线拟合，一般建议采用4参数曲线拟合，4参数曲线拟合通常更适合免疫分析。推荐使用专业软件进行曲线拟合，例如curve expert 1.3。根据样本的OD值由标曲查出相应的浓度，再乘以稀释倍数；或用标准物的浓度与OD值计算出标曲的回归方程式，将样本的OD值代入方程式，计算出样本浓度，再乘以稀释倍数，即为样本的实际浓度。以下链接是curve expert 1.3软件拟合曲线的方法。

人KCNAB1ELISA试剂盒中是否包含人和动物的副产物，是否包含感染的或者传染性原料如HIV等？

除了抗体和稀释液中的BSA，不含其它人和动物的副产物，也不含感染材料。

[8].

收集人KCNAB1ELISA试剂盒血浆样本，用什么作为抗凝剂？

一般建议用EDTA和肝素作为抗凝剂。

[9].

人KCNAB1ELISA试剂盒酶标板可以拆成几部分？拆的时候是否需要避光，无菌？

人KCNAB1ELISA试剂盒酶标板是8×12孔条，可拆卸，板子可以拆成12条，注意避免孔污染，不需要避光和无菌。暂时不用的板子，放回原来装的袋子里，密封保存。

[10].

人KCNAB1ELISA试剂盒样本如何保存？

尽量检测新鲜样本。若无新鲜样本，则4℃保存1周，-20℃保存1个月，-80℃保存2个月。
