抗體的生物素化標記實驗要點:
1. 神經(jīng)細胞分化因子1抗體說明書 如在反應混合液中有疊氮鈉或游離氨基存在,會抑制標記反應。因此,蛋白質(zhì)在反應前要對 0.1mol/L碳酸氫鈉緩沖液或0.5mol/L硼酸緩沖液充分透析;
2.所用的NHSB及待生物素化蛋白質(zhì)之間的分子比按蛋白質(zhì)表面的ε-氨基的密度會有所不同,選擇不當則影響標記的效率,應先用幾個不同的分子比來篩選最適條件;
3.用NHSB量過量也是不利的,抗原的結(jié)合位點可能因此被封閉,導致抗體失活;
4.由于抗體的氨基不易接近可能造成生物素化不足,此時可加入去污劑如 Triton x-100, Tween20等;
5.當游離ε-氨基(賴氨酸殘基的氨基)存在于抗體的抗原結(jié)合位點時,或位于酶的催化位點時,生物素化會降低或損傷抗體蛋白的結(jié)合力或活性;
6.生物素還可能與不同的功能基團,如羰基、氨基、巰基、異咪唑基及*基,也可與糖基共價結(jié)合;
7.交聯(lián)反應后,應充分透析,否則,殘余的生物素會對生物素化抗體與親和素的結(jié)合產(chǎn)生競爭作用;
8.在細胞的熒光標記實驗中,中和親和素的本底低,但由于鏈霉親和素含有少量正電荷,故對某些細胞可導致高本底。

產(chǎn)品介紹 NeuroD1 (Neurogenic Differentiation factor 1, also known as BETA2, beta-cell E-box transactivator 2) is a 40kDa protein, a member of the bHLH family. NeuroD1 is a homolog of the Drosophila atonal gene. NeuroD1 is widely expressed during development in the mammalian brain and pancreas where it acts as a transcriptional activator, and binds to insulin gene E-box. NeuroD1 has also been reported to be a differentiation factor in neurogenesis. Changes in NeuroD1 gene expression have been linked to diabetes mellitus type II and maturity-onset diabetes of the young type VI. NeuroD1 expression can be induced by glucose in beta cells.
Function : Acts as a transcriptional activator: mediatestranscriptional activation by binding to E box-containing promoterconsensus core sequences 5'-CANNTG-3'. Associates with the p300/CBPtranscription coactivator complex to stimulate transcription of thesecretin gene as well as the gene encoding the cyclin-dependentkinase inhibitor CDKN1A. Contributes to the regulation of severalcell differentiation pathways, like those that promote theformation of early retinal ganglion cells, inner ear sensoryneurons, granule cells forming either the cerebellum or the dentategyrus cell layer of the hippocampus, endocrine islet cells of thepancreas and enteroendocrine cells of the small intestine. Togetherwith PAX6 or SIX3, is required for the regulation of amacrine cellfate specification. Also required for dendrite morphogenesis andmaintenance in the cerebellar cortex. Associates with chromatin toenhancer regulatory elements in genes encoding key transcriptionalregulators of neurogenesis (By similarity).Subunit : Interacts (via helix-loop-helix motif domain) with EP300(via C-terminus) (By similarity). Heterodimer with TCF3/E47; theheterodimer is inhibited in presence of ID2, but not NR0B2, toE-box element. Efficient DNA-binding requires dimerization withanother bHLH protein. Interacts with RREB1. Interacts with EP300;the interaction is inhibited by NR0B2. Interacts with TCF3; theinteraction is inhibited by ID2.Subcellular Location : Cytoplasm (By similarity). Nucleus. Note=Inpancreatic islet cells, shuttles to the nucleus in response toglucose stimulation (By similarity). Colocalizes with NR0B2 in thenucleus.Post-translational modifications : Phosphorylated. In islet cells, phosphorylated on Ser-274upon glucose stimulation; which may be required for nuclearlocalization. In activated neurons, phosphorylated on Ser-335;which promotes dendritic growth. Phosphorylated by MAPK1;phosphorylation regulates heterodimerization and DNA-bindingactivities. Phosphorylation on Ser-266 and Ser-274 increasestransactivation on the insulin promoter in glucose-stimulatedinsulinoma cells (By similarity).DISEASE : Maturity-onset diabetes of the young 6 (MODY6)[MIM:606394]: A form of diabetes that is characterized by anautosomal dominant mode of inheritance, onset in childhood or earlyadulthood (usually before 25 years of age), a primary defect ininsulin secretion and frequent insulin-independence at thebeginning of the disease. Note=The disease is caused by mutationsaffecting the gene represented in this entry.Similarity : Contains 1 bHLH (basic helix-loop-helix) domain.Database links : UniProtKB/Swiss-Prot: Q13562.3神經(jīng)生物學相關(guān)蛋白(Neurobiology)
抗體的鑒定:
1)神經(jīng)細胞分化因子1抗體說明書 抗體的效價鑒定:不管是用于診斷還是用于,制備抗體的目的都是要求較高效價。不同的抗原制備的抗體,要求的效價不一。鑒定效價的方法很多,包括有試管凝集反應,瓊脂擴散試驗,酶聯(lián)免疫吸附試驗等。常用的抗原所制備的抗體一般都有約成的鑒定效價的方法,以資比較。如制備抗抗體的效價,一般就采用瓊脂擴散試驗來鑒定。
2)抗體的特異性鑒定:抗體的特異性是指與相應抗原或近似抗原物質(zhì)的識別能力??贵w的特異性高,它的識別能力就強。衡量特異性通常以交叉反應率來表示。交叉反應率可用競爭抑制試驗測定。以不同濃度抗原和近似抗原分別做競爭抑制曲線,計算各自的結(jié)合率,求出各自在IC50時的濃度,并按公式計算交叉反應率。
如果所用抗原濃度IC50濃度為pg/管,而一些近似抗原物質(zhì)的IC50濃度幾乎是無窮大時,表示這一抗血清與其他抗原物質(zhì)的交叉反應率近似為0,即該血清的特異性較好。
3)抗體親和力:是指抗體和抗原結(jié)合的牢固程度。親和力的高低是由抗原分子的大小,抗體分子的結(jié)合位點與抗原決定簇之間立體構(gòu)型的合適度決定的。有助于維持抗原抗體復合物穩(wěn)定的分子間力有氫鍵,疏水鍵,側(cè)鏈相反電荷基因的庫侖力,范德華力和空間斥力。親和力常以親和常數(shù)K表示,K的單位是L/mol??贵w親和力的測定對抗體的篩選,確定抗體的用途,驗證抗體的均一性等均有重要意義。
