详细介绍

实验原理 :

1)公司产品仅用于科研特异性结合抗原:抗体本身不能直接溶解或杀伤带有特异抗原的靶细胞,通常需要补体或吞噬细胞等共同发挥效应以清除病原微生物或导致病理损伤。然而,抗体可通过与病毒或毒素的特异性结合,直接发挥中和病毒的作用。

2)活补体:IgM、IgG1、IgG2和IgG3可通过经典途径激活补体,凝聚的IgA、IgG4和IgE可通过替代途径激活补体。

3)结合细胞:不同类别的免疫球蛋白,可结合不同种的细胞,参与免疫应答。

4)可通过胎盘及粘膜:免疫球蛋白G(IgG)能通过胎盘进入胎儿血流中,使胎儿形成自然被动免疫。免疫球蛋白A(IgA)可通过消化道及呼吸道粘膜,是粘膜局部抗感染免疫的主要因素。

5)具有抗原性:抗体分子是一种蛋白质,也具有刺机体产生免疫应答的性能。不同的免疫球蛋白分子,各具有不同的抗原性。

6)抗体对理化因子的抵抗力与一般球蛋白相同:不耐热,60~70℃即被破坏。各种酶及能使蛋白质凝固变性的物质,均能破坏抗体的作用。抗体可被中性盐类沉淀。在生产上常可用硫酸铵或硫酸钠从免疫血清中沉淀出含有抗体的球蛋白,再经透析法将其纯化。

产品介绍:This gene encodes a member of the RSK (ribosomal S6 kinase) family of serine/threonine kinases. This kinase contains 2 non-identical kinase catalytic domains and phosphorylates various substrates, including members of the mitogen-activated kinase (MAPK) signalling pathway. The activity of this protein has been implicated in controlling cell growth and differentiation. Mutations in this gene have been associated with Coffin-Lowry syndrome (CLS). [provided by RefSeq, Jul 2008]

Function:

Serine/threonine-protein kinase that acts downstream of ERK (MAPK1/ERK2 and MAPK3/ERK1) signaling and mediates mitogenic and stress-induced activation of the transcription factors CREB1, ETV1/ER81 and NR4A1/NUR77, regulates translation through RPS6 and EIF4B phosphorylation, and mediates cellular proliferation, survival, and differentiation by modulating mTOR signaling and repressing pro-apoptotic function of BAD and DAPK1. In fibroblast, is required for EGF-stimulated phosphorylation of CREB1 and histone H3 at 'Ser-10', which results in the subsequent transcriptional activation of several immediate-early genes. In response to mitogenic stimulation (EGF and PMA), phosphorylates and activates NR4A1/NUR77 and ETV1/ER81 transcription factors and the cofactor CREBBP. Upon insulin-derived signal, acts indirectly on the transcription regulation of several genes by phosphorylating GSK3B at 'Ser-9' and inhibiting its activity. Phosphorylates RPS6 in response to serum or EGF via an mTOR-independent mechanism and promotes translation initiation by facilitating assembly of the preinitiation complex. In response to insulin, phosphorylates EIF4B, enhancing EIF4B affinity for the EIF3 complex and stimulating cap-dependent translation. Is involved in the mTOR nutrient-sensing pathway by directly phosphorylating TSC2 at 'Ser-1798', which potently inhibits TSC2 ability to suppress mTOR signaling, and mediates phosphorylation of RPTOR, which regulates mTORC1 activity and may promote rapamycin-sensitive signaling independently of the PI3K/AKT pathway. Mediates cell survival by phosphorylating the pro-apoptotic proteins BAD and DAPK1 and suppressing their pro-apoptotic function. Promotes the survival of hepatic stellate cells by phosphorylating CEBPB in response to the hepatotoxin carbon tetrachloride (CCl4). Is involved in cell cycle regulation by phosphorylating the CDK inhibitor CDKN1B, which promotes CDKN1B association with 14-3-3 proteins and prevents its translocation to the nucleus and inhibition of G1 progression. In LPS-stimulated dendritic cells, is involved in TLR4-induced macropinocytosis, and in myeloma cells, acts as effector of FGFR3-mediated transformation signaling, after direct phosphorylation at Tyr-529 by FGFR3. Phosphorylates DAPK1.

抗体的标记实验要点:

1.如在反应混合液中有叠氮钠或游离氨基存在,会抑制标记反应。因此,蛋白质在反应前要对 0.1mol/L缓冲液或0.5mol/L硼酸缓冲液充分透析;

2.所用的NHSB及待化蛋白质之间的分子比按蛋白质表面的ε-氨基的密度会有所不同,选择不当则影响标记的效率,应先用几个不同的分子比来筛选最适条件;

3.用NHSB量过量也是不利的,抗原的结合位点可能因此被封闭,导致抗体失活;

4.由于抗体的氨基不易接近可能造成化不足,此时可加入去污剂如 Triton x-100, Tween20等;

5.当游离ε-氨基(赖氨酸残基的氨基)存在于抗体的抗原结合位点时,或位于酶的催化位点时,化会降低或损伤抗体蛋白的结合力或活性;

6.还可能与不同的功能基团,如羰基、氨基、巯基、异咪唑基及基,也可与糖基共价结合;

7.交联反应后,应充分透析,否则,残余的会对化抗体与亲和素的结合产生竞争作用;

8.在细胞的荧光标记实验中,中和亲和素的本底低,但由于链霉亲和素含有少量正电荷,故对某些细胞可导致高本底。
一抗和二抗的区别:

第一抗体就是平常所说的抗体,即能和抗原特异性结合。

第二抗体是能和抗体结合的,即抗体的抗体。主要用于检测抗体的存在。

一抗是针对抗原的抗体,二抗是针对一抗的抗体。即抗体也可以充当抗原刺激机体产生抗体。也就是说,抗原进入机体刺激机体免疫系统产生免疫应答,由B细胞可以产生与相应抗原发生特异性结合的特殊蛋白质。

一抗二抗都是一种可以特异结合别的物质的基团,而且一抗可以至少结合两种其他基团(底物和二抗)。

一抗:可以特异结合底物,就是识别出我们想要检测的东西。一抗和底物结合与否用肉眼是看不出来的。

二抗:可以和一抗结合,并带有可以被检测出的标记(如带荧光、放射性、化学发光或显色基团),作用是检测一抗。 如果一抗自己带有可以被检测出的标记(如带荧光、放射性、化学发光或显色基团),则不需要二抗。但这样成本很高,因为一种一抗只识别一种底物。所以如今的设计一般是二抗带上可检测标记,再来检测一抗。而一抗识别底物。这样,当一抗结合到底物上,就可以通过二抗检测出来。
