抗體的生物素化標(biāo)記實(shí)驗(yàn)要點(diǎn)：

1. 磷酸化突觸蛋白6抗體規(guī)格 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)生競爭作用；

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 Synaptotagmins (Syts) are a large gene family of synaptic vesicle integral membrane proteins. Syt functions as regulators of both exocytosis /endocytosis and is involved in neurotransmitter secretion from small secretory vesicles. 13 isoforms of Syt have been identified(SytI-XIII). SynaptotagminVI is localized to the endoplasmic reticulum and/or Golgi like perinuclear compartment. It may be important for trafficking and calcium signaling as it is specially expressed in nonneuronal tissues. Also SytVI is present in the acrosomal region of mammalian spermatozoa. The cytosolic domain of SytVI can abrogate exocytosis by competing with the endogenous protein for essential interactions with the fusion machinery involved in a acrosomal exocytosis.

Function : May be involved in Ca(2+)-dependent exocytosis of secretory vesicles through Ca(2+) and phospholipid binding to the C2 domain or may serve as Ca(2+) sensors in the process of vesicular trafficking and exocytosis. May mediate Ca(2+)-regulation of exocytosis in acrosomal reaction in sperm (By similarity).

Subunit : Homodimer (isoform 1). Isoform 1 forms heterodimers with SytIII, SytV and SytX. Interacts with STX1A, STX1B and STX2; the interaction is Ca(2+)-dependent. Isoform 2 is not able to form homodimer and heterodimers (By similarity).

Subcellular Location : Cytoplasmic vesicle, secretory vesicle, synaptic vesicle membrane; Single-pass membrane protein (By similarity).

Isoform 1: Membrane; Single-pass membrane protein (By similarity). Note=Localized predominantly to endoplasmic reticulum (ER) and/or Golgi-like perinuclear compartment (By similarity).

Isoform 2: Cytoplasm, cytosol (By similarity). Cell membrane; Peripheral membrane protein (By similarity).

Similarity : Belongs to the synaptotagmin family.

Contains 2 C2 domains.

抗體的鑒定：

1）磷酸化突觸蛋白6抗體規(guī)格 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)率來表示。交叉反應(yīng)率可用競爭抑制試驗(yàn)測定。以不同濃度抗原和近似抗原分別做競爭抑制曲線,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/管,而一些近似抗原物質(zhì)的IC50濃度幾乎是無窮大時(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(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。
