抗体的生物素化标记实验要点：

1. 磷酸化血小板源性生长因子受体B抗体规格 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碳酸氢钠缓冲液或0.5mol/L硼酸缓冲液充分透析；

2.所用的NHSB及待生物素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生物素化不足,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,生物素化会降低或损伤抗体蛋白的结合力或活性；

6.生物素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,残余的生物素会对生物素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。

产品介绍 This gene encodes a cell surface tyrosine kinase receptor for members of the platelet-derived growth factor family. These growth factors are mitogens for cells of mesenchymal origin. The identity of the growth factor bound to a receptor monomer determines whether the functional receptor is a homodimer or a heterodimer, composed of both platelet-derived growth factor receptor alpha and beta polypeptides. This gene is flanked on chromosome 5 by the genes for granulocyte-macrophage colony-stimulating factor and macrophage-colony stimulating factor receptor; all three genes may be implicated in the 5-q syndrome. A translocation between chromosomes 5 and 12, that fuses this gene to that of the translocation, ETV6, leukemia gene, results in chronic myeloproliferative disorder with eosinophilia.

Function : Tyrosine-protein kinase that acts as cell-surface receptor for homodimeric PDGFB and PDGFD and for heterodimers formed by PDGFA and PDGFB, and plays an essential role in the regulation of embryonic development, cell proliferation, survival, differentiation, chemotaxis and migration. Plays an essential role in blood vessel development by promoting proliferation, migration and recruitment of pericytes and smooth muscle cells to endothelial cells. Plays a role in the migration of vascular smooth muscle cells and the formation of neointima at vascular injury sites. Required for normal development of the cardiovascular system. Required for normal recruitment of pericytes (mesangial cells) in the kidney glomerulus, and for normal formation of a branched network of capillaries in kidney glomeruli. Promotes rearrangement of the actin cytoskeleton and the formation of membrane ruffles. Binding of its cognate ligands - homodimeric PDGFB, heterodimers formed by PDGFA and PDGFB or homodimeric PDGFD -leads to the activation of several signaling cascades; the response depends on the nature of the bound ligand and is modulated by the formation of heterodimers between PDGFRA and PDGFRB. Phosphorylates PLCG1, PIK3R1, PTPN11, RASA1/GAP, CBL, SHC1 and NCK1. Activation of PLCG1 leads to the production of the cellular signaling molecules diacylglycerol and inositol 1,4,5-trisphosphate, mobilization of cytosolic Ca(2+) and the activation of protein kinase C. Phosphorylation of PIK3R1, the regulatory subunit of phosphatidylinositol 3-kinase, leads to the activation of the AKT1 signaling pathway. Phosphorylation of SHC1, or of the C-terminus of PTPN11, creates a binding site for GRB2, resulting in the activation of HRAS, RAF1 and down-stream MAP kinases, including MAPK1/ERK2 and/or MAPK3/ERK1. Promotes phosphorylation and activation of SRC family kinases. Promotes phosphorylation of PDCD6IP/ALIX and STAM. Receptor signaling is down-regulated by protein phosphatases that dephosphorylate the receptor and its down-stream effectors, and by rapid internalization of the activated receptor.

Subunit : Interacts with homodimeric PDGFB and PDGFD, and with heterodimers formed by PDGFA and PDGFB. May also interact with homodimeric PDGFC. Monomer in the absence of bound ligand. Interaction with homodimeric PDGFB, heterodimers formed by PDGFA and PDGFB or homodimeric PDGFD, leads to receptor dimerization, where both PDGFRA homodimers and heterodimers with PDGFRB are observed. Interacts with SH2B2/APS. Interacts directly (tyrosine phosphorylated) with SHB. Interacts (tyrosine phosphorylated) with PIK3R1. Interacts (tyrosine phosphorylated) with CBL. Interacts (tyrosine phosphorylated) with SRC and SRC family kinases. Interacts (tyrosine phosphorylated) with PIK3C2B, maybe indirectly. Interacts (tyrosine phosphorylated) with SHC1, GRB7, GRB10 and NCK1. Interaction with GRB2 is mediated by SHC1. Interacts (via C-terminus) with SLC9A3R1.

Subcellular Location : Cell membrane; Single-pass type I membrane protein. Cytoplasmic vesicle. Lysosome lumen. Note=After ligand binding, the autophosphorylated receptor is ubiquitinated and internalized, leading to its degradation

Ubiquitinated. After autophosphorylation, the receptor is polyubiquitinated, leading to its degradation.

DISEASE : Note=A chromosomal aberration involving PDGFRB is found in a form of chronic myelomonocytic leukemia (CMML). Translocation t(5;12)(q33;p13) with EVT6/TEL. It is characterized by abnormal clonal myeloid proliferation and by progression to acute myelogenous leukemia (AML).

Note=A chromosomal aberration involving PDGFRB may be a cause of juvenile myelomonocytic leukemia. Translocation t(5;17)(q33;p11.2) with SPECC1.

Defects in PDGFRB are a cause of myeloproliferative disorder chronic with eosinophilia (MPE) [MIM:131440]. A hematologic disorder characterized by malignant eosinophils proliferation. Note=A chromosomal aberration involving PDGFRB is found in many instances of myeloproliferative disorder chronic with eosinophilia. Translocation t(5;12) with ETV6 on chromosome 12 creating an PDGFRB-ETV6 fusion protein. Translocation t(5;15)(q33;q22) with TP53BP1 creating a PDGFRB-TP53BP1 fusion protein.

Note=A chromosomal aberration involving PDGFRB may be the cause of a myeloproliferative disorder (MBD) associated with eosinophilia. Translocation t(1;5)(q23;q33) that forms a PDE4DIP-PDGFRB fusion protein.

Note=A chromosomal aberration involving PGFRB is found in a patient with T-lymphoblastic lymphoma (T-ALL) and an associated myeloproliferative neoplasm (MPN) with eosinophilia. Translocation t(5;6)(q33-34;q23) with CEP85L. The translocation fuses the 5'-end of CEP85L (isoform 4) to the 3'-end of PDGFRB.

抗体的鉴定：

1）磷酸化血小板源性生长因子受体B抗体规格 抗体的效价鉴定：不管是用于诊断还是用于,制备抗体的目的都是要求较高效价。不同的抗原制备的抗体,要求的效价不一。鉴定效价的方法很多,包括有试管凝集反应,琼脂扩散试验,酶联免疫吸附试验等。常用的抗原所制备的抗体一般都有约成的鉴定效价的方法,以资比较。如制备抗抗体的效价,一般就采用琼脂扩散试验来鉴定。

2）抗体的特异性鉴定：抗体的特异性是指与相应抗原或近似抗原物质的识别能力。抗体的特异性高,它的识别能力就强。衡量特异性通常以交叉反应率来表示。交叉反应率可用竞争抑制试验测定。以不同浓度抗原和近似抗原分别做竞争抑制曲线,计算各自的结合率,求出各自在IC50时的浓度,并按公式计算交叉反应率。 

如果所用抗原浓度IC50浓度为pg/管,而一些近似抗原物质的IC50浓度几乎是无穷大时,表示这一抗血清与其他抗原物质的交叉反应率近似为0,即该血清的特异性较好。

3）抗体亲和力：是指抗体和抗原结合的牢固程度。亲和力的高低是由抗原分子的大小,抗体分子的结合位点与抗原决定簇之间立体构型的合适度决定的。有助于维持抗原抗体复合物稳定的分子间力有氢键,疏水键,侧链相反电荷基因的库仑力,范德华力和空间斥力。亲和力常以亲和常数K表示,K的单位是L/mol。抗体亲和力的测定对抗体的筛选,确定抗体的用途,验证抗体的均一性等均有重要意义。
