產(chǎn)品介紹 SCUBE3 is a novel secreted 993 amino acid cell-surface osteoblast protein that plays an important role in bone cell biology. While highly expressed in osteoblasts, SCUBE3 expression is unobservable or very low in non-bone tissues. SCUBE3 forms homo-oligomers and hetero-oligomers with SCUBE1, and may undergo C-terminal proteolytic cleavage or become N-glycosylated following translation. Two SCUBE3 isoforms exist as a result of alternative splicing events. SCUBE3 contains one CUB domain and nine EGF-like domains, and is encoded by a gene which maps to human chromosome 6p21.31, a region associated with a rare form of metabolic bone disease known as Paget's disease. Chromosome 6 contains 170 million base pairs and comprises nearly 6% of the human genome.

Function : Binds to TGFBR2 and activates TGFB signaling. In lungcancer cells, could serve as an endogenous autocrine and paracrineligand of TGFBR2, which could regulate TGFBR2 signaling and hencemodulate epithelial-mesenchymal transition and cancer progression.

Subunit : Forms homooligomers and heterooligomers with SCUBE1.Interacts with TGFBR2 through the CUB domain; this interaction doesnot affect TGFB1-binding to TGFBR2.

Subcellular Location : Secreted. Cell surface.

Tissue Specificity : Highly expressed in osteoblasts. Expression is low or absent in non-bone tissues.

Post-translational modifications : N-glycosylated.

May undergo proteolytic cleavage in the C-terminal region.

Similarity : Contains 1 CUB domain.

Contains 9 EGF-like domains.

抗體的生物素化標(biāo)記實驗要點：

1. 新型分泌細(xì)胞表面蛋白/成骨細(xì)胞相關(guān)蛋白SCUBE3抗體說明書 如在反應(yīng)混合液中有疊氮鈉或游離氨基存在,會抑制標(biāo)記反應(yīng)。因此,蛋白質(zhì)在反應(yīng)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(dāng)則影響標(biāo)記的效率,應(yīng)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(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(tuán),如羰基、氨基、巰基、異咪唑基及苯酚基,也可與糖基共價結(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(xì)胞的熒光標(biāo)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(xì)胞可導(dǎo)致高本底。

抗體的鑒定：

1）新型分泌細(xì)胞表面蛋白/成骨細(xì)胞相關(guān)蛋白SCUBE3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(yīng),瓊脂擴(kuò)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(kuò)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(yīng)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(yīng)率來表示。交叉反應(yīng)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(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,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。
