抗體的生物素化標(biāo)記實(shí)驗(yàn)要點(diǎn):

1. 端粒調(diào)控因子抗體費(fèi)用 如在反應(yīng)混合液中有疊氮鈉或游離氨基存在,會(huì)抑制標(biāo)記反應(yīng)。因此,蛋白質(zhì)在反應(yīng)前要對(duì) 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(huì)有所不同,選擇不當(dāng)則影響標(biāo)記的效率,應(yīng)先用幾個(gè)不同的分子比來(lái)篩選最適條件;

3.NHSB量過(guò)量也是不利的,抗原的結(jié)合位點(diǎn)可能因此被封閉,導(dǎo)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(shí)可加入去污劑如 Triton x-100, Tween20等;

5.當(dāng)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(diǎn)時(shí),或位于酶的催化位點(diǎn)時(shí),生物素化會(huì)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(tuán),如羰基、氨基、巰基、異咪唑基及苯酚基,也可與糖基共價(jià)結(jié)合;

7.交聯(lián)反應(yīng)后,應(yīng)充分透析,否則,殘余的生物素會(huì)對(duì)生物素化抗體與親和素的結(jié)合產(chǎn)生競(jìng)爭(zhēng)作用;

8.在細(xì)胞的熒光標(biāo)記實(shí)驗(yàn)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(duì)某些細(xì)胞可導(dǎo)致高本底。

產(chǎn)品介紹 Tankyrase-1 and the closely related homolog Tankyrase-2 arepoly(ADP-ribose) polymerases (PARPs) that co-localize and use an ankyrin-repeat domain to bind diverse proteins, including TRF-1 (telomere-repeat-binding factor 1), IRAP (insulin-responsive aminopeptidase) and TAB182. Tankyrase-1 (also known as TNKS and TNKS1) and Tankyrase-2 (also known as TNKS2, TNKL and TANK2) interact with the same set of proteins and probably mediate overlapping functions, both at telomeres and in vesicular compartments. Overexpression of Tankyrase-1 in the nucleus promotes telomere elongation, suggesting that Tankyrase 1 may regulate access of telomerase to the telomeric complex. Overexpression of Tankyrase-2 in the nucleus releases endogenous TRF1 from telomeres, establishing Tankyrase-2 as a PARP with itself and TRF1 as acceptors of ADP-ribosylation, and suggesting the possibility of a role for Tankyrase-2 at telomeres. The ankyrin (ANK) domain of Tankyrase-2 comprises five subdomains that provide redundant binding sites for IRAP. Tankyrase-2 lacks the N-terminal Histidine/Proline/Serine-rich region of Tankyrase-1, but contains a corresponding ankyrin repeat region, sterile ?motif module and poly(ADP-ribose) polymerase homology domain. The gene encoding Tankyrase-2 is widely expressed, with mRNA transcripts particularly abundant in skeletal muscle and placenta.

Subunit : Oligomerizes and associates with TNKS2. Interacts with the cytoplasmic domain of LNPEP/Otase in SLC2A4/GLUT4-vesicles. Binds to the N-terminus of telomeric TERF1 via the ANK repeats. Found in a complex with POT1; TERF1 and TINF2. Interacts with AXIN1, AXIN2, BLZF1 and CASC3.

Subcellular Location : Cytoplasm. Golgi apparatus membrane. Chromosome > centromere. Nucleus > nuclear pore complex. Chromosome > telomere. Associated with the Golgi and with juxtanuclear SLC2A4/GLUT4-vesicles. A minor proportion is also found at nuclear pore complexes and around the pericentriolar matrix of mitotic centromeres. During interphase, a small fraction of TNKS is found in the nucleus, associated with TERF1.

Tissue Specificity : Ubiquitous; highest levels in testis.

Similarity : Contains 15 ANK repeats.

Contains 1 PARP catalytic domain.

Contains 1 SAM (sterile alpha motif) domain.

抗體的鑒定:

1端粒調(diào)控因子抗體費(fèi)用 抗體的效價(jià)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(jià)。不同的抗原制備的抗體,要求的效價(jià)不一。鑒定效價(jià)的方法很多,包括有試管凝集反應(yīng),瓊脂擴(kuò)散試驗(yàn),酶聯(lián)免疫吸附試驗(yàn)等。常用的抗原所制備的抗體一般都有約成的鑒定效價(jià)的方法,以資比較。如制備抗抗體的效價(jià),一般就采用瓊脂擴(kuò)散試驗(yàn)來(lái)鑒定。

2)抗體的特異性鑒定:抗體的特異性是指與相應(yīng)抗原或近似抗原物質(zhì)的識(shí)別能力??贵w的特異性高,它的識(shí)別能力就強(qiáng)。衡量特異性通常以交叉反應(yīng)率來(lái)表示。交叉反應(yīng)率可用競(jìng)爭(zhēng)抑制試驗(yàn)測(cè)定。以不同濃度抗原和近似抗原分別做競(jìng)爭(zhēng)抑制曲線,計(jì)算各自的結(jié)合率,求出各自在IC50時(shí)的濃度,并按公式計(jì)算交叉反應(yīng)率。 

如果所用抗原濃度IC50濃度為pg/,而一些近似抗原物質(zhì)的IC50濃度幾乎是無(wú)窮大時(shí),表示這一抗血清與其他抗原物質(zhì)的交叉反應(yīng)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(diǎn)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(fù)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(kù)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。抗體親和力的測(cè)定對(duì)抗體的篩選,確定抗體的用途,驗(yàn)證抗體的均一性等均有重要意義。
