鈉碘轉(zhuǎn)運(yùn)體蛋白8抗體別 名:AIT; Apical iodide transporter; Electrogenic sodium monocarboxylate cotransporter; SC5A8_HUMAN; SLC5A8; SMCT; SMCT1; sodium coupled monocarboxylate transporter 1; Sodium iodide relate

實(shí)驗(yàn)原理 :

（1）公司產(chǎn)品僅用于科研特異性結(jié)合抗原：抗體本身不能直接溶解或殺傷帶有特異抗原的靶細(xì)胞，通常需要補(bǔ)體或吞噬細(xì)胞等共同發(fā)揮效應(yīng)以清除病原微生物或?qū)е虏±頁(yè)p傷。然而，抗體可通過與病毒或毒素的特異性結(jié)合，直接發(fā)揮中和病毒的作用。

（2）活補(bǔ)體：IgM、IgG1、IgG2和IgG3可通過經(jīng)典途徑激活補(bǔ)體，凝聚的IgA、IgG4和IgE可通過替代途徑激活補(bǔ)體。

（3）結(jié)合細(xì)胞：不同類別的免疫球蛋白，可結(jié)合不同種的細(xì)胞，參與免疫應(yīng)答。

（4）可通過胎盤及粘膜：免疫球蛋白G（IgG）能通過胎盤進(jìn)入胎兒血流中，使胎兒形成自然被動(dòng)免疫。免疫球蛋白A（IgA）可通過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：抗體分子是一種蛋白質(zhì)，也具有刺機(jī)體產(chǎn)生免疫應(yīng)答的性能。不同的免疫球蛋白分子，各具有不同的抗原性。

（6）抗體對(duì)理化因子的抵抗力與一般球蛋白相同：不耐熱，60～70℃即被破壞。各種酶及能使蛋白質(zhì)凝固變性的物質(zhì)，均能破壞抗體的作用。抗體可被中性鹽類沉淀。在生產(chǎn)上常可用硫酸銨或硫酸鈉從免疫血清中沉淀出含有抗體的球蛋白，再經(jīng)透析法將其純化。

產(chǎn)品介紹:Acts as an electrogenic sodium (Na(+)) and chloride (Cl-)-dependent sodium-coupled solute transporter, including transport of monocarboxylates (short-chain fatty acids including L-lactate, D-lactate, pyruvate, acetate, propionate, valerate and butyrate), lactate, mocarboxylate drugs (nicotinate, benzoate, salicylate and 5-aminosalicylate) and ketone bodies (beta-D-hydroxybutyrate, acetoacetate and alpha-ketoisocaproate), with a Na(+):substrate stoichiometry of between 4:1 and 2:1. Catalyzes passive carrier mediated diffusion of iodide. Mediates iodide transport from the thyrocyte into the colloid lumen through the apical membrane. May be responsible for the absorption of D-lactate and monocarboxylate drugs from the intestinal tract. Acts as a tumor suppressor, suppressing colony formation in colon cancer, prostate cancer and glioma cell lines. May play a critical role in the entry of L-lactate and ketone bodies into neurons by a process driven by an electrochemical Na(+) gradient and hence contribute to the maintenance of the energy status and function of neurons.

商品屬性：

抗體的標(biāo)記實(shí)驗(yàn)要點(diǎn)：

1.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緩沖液或0.5mol/L硼酸緩沖液充分透析；

2.所用的NHSB及待化蛋白質(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(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),化會(huì)降低或損傷抗體蛋白的結(jié)合力或活性；

6.還可能與不同的功能基團(tuán),如羰基、氨基、巰基、異咪唑基及基,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,殘余的會(huì)對(duì)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。
一抗和二抗的區(qū)別：

第一抗體就是平常所說的抗體，即能和抗原特異性結(jié)合。

第二抗體是能和抗體結(jié)合的，即抗體的抗體。主要用于檢測(cè)抗體的存在。

一抗是針對(duì)抗原的抗體，二抗是針對(duì)一抗的抗體。即抗體也可以充當(dāng)抗原刺激機(jī)體產(chǎn)生抗體。也就是說，抗原進(jìn)入機(jī)體刺激機(jī)體免疫系統(tǒng)產(chǎn)生免疫應(yīng)答，由B細(xì)胞可以產(chǎn)生與相應(yīng)抗原發(fā)生特異性結(jié)合的特殊蛋白質(zhì)。

一抗二抗都是一種可以特異結(jié)合別的物質(zhì)的基團(tuán)，而且一抗可以至少結(jié)合兩種其他基團(tuán)（底物和二抗）。

一抗：可以特異結(jié)合底物，就是識(shí)別出我們想要檢測(cè)的東西。一抗和底物結(jié)合與否用肉眼是看不出來的。

二抗：可以和一抗結(jié)合，并帶有可以被檢測(cè)出的標(biāo)記(如帶熒光、放射性、化學(xué)發(fā)光或顯色基團(tuán)），作用是檢測(cè)一抗。 如果一抗自己帶有可以被檢測(cè)出的標(biāo)記(如帶熒光、放射性、化學(xué)發(fā)光或顯色基團(tuán)），則不需要二抗。但這樣成本很高，因?yàn)橐环N一抗只識(shí)別一種底物。所以如今的設(shè)計(jì)一般是二抗帶上可檢測(cè)標(biāo)記，再來檢測(cè)一抗。而一抗識(shí)別底物。這樣，當(dāng)一抗結(jié)合到底物上，就可以通過二抗檢測(cè)出來。
