通用注释

亚单元:

Proposed to be monomeric or homodimeric in nucleotide-free form and to oligomerize upon binding to ATP to form two stacked hexameric or heptameric rings with a central pore through which ESCRT-III substrates are translocated in an ATP-dependent manner (By similarity). Interacts with CHMP1A, CHMP1B, CHMP2A, CHMP2B, CHMP3, CHMP4A, CHMP4B, CHMP4C and CHMP6. Interacts with VPS4B; the interaction suggests a heteromeric assembly with VPS4B. Interacts with SPAST. Interacts with IST1. Interacts with ZFYVE19/ANCHR; leading to retain it at midbody.

功能:

Involved in late steps of the endosomal multivesicular bodies (MVB) pathway. Recognizes membrane-associated ESCRT-III assemblies and catalyzes their disassembly, possibly in combination with membrane fission. Redistributes the ESCRT-III components to the cytoplasm for further rounds of MVB sorting. MVBs contain intraluminal vesicles (ILVs) that are generated by invagination and scission from the limiting membrane of the endosome and mostly are delivered to lysosomes enabling degradation of membrane proteins, such as stimulated growth factor receptors, lysosomal enzymes and lipids. In conjunction with the ESCRT machinery also appears to function in topologically equivalent membrane fission events, such as the terminal stages of cytokinesis and enveloped virus budding (HIV-1 and other lentiviruses). Involved in cytokinesis: retained at the midbody by ZFYVE19/ANCHR and CHMP4C until abscission checkpoint signaling is terminated at late cytokinesis. It is then released following dephosphorylation of CHMP4C, leading to abscission (PubMed:24814515). VPS4A/B are required for the exosomal release of SDCBP, CD63 and syndecan (PubMed:22660413).

亚细胞位置:

Prevacuolar compartment membrane Peripheral membrane protein Late endosome membrane Peripheral membrane protein Midbody Membrane-associated in the prevacuolar endosomal compartment. Localizes to the midbody of dividing cells, interaction with ZFYVE19/ANCHR mediates retention at midbody (PubMed:24814515). Localized in two distinct rings on either side of the Flemming body.

人VPS4AELISA试剂盒是放在-20℃冰箱保存吗？

EIAab的人VPS4AELISA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VPS4AELISA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VPS4AELISA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VPS4AELISA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VPS4AELISA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VPS4AELISA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VPS4AELISA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VPS4AELISA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VPS4AELISA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。
