產品介紹 This gene encodes a glycosylphosphatidylinositol-anchored cell membrane glycoprotein. In addition to being highly expressed in the prostate it is also expressed in the bladder, placenta, colon, kidney, and stomach. This gene is up-regulated in a large proportion of prostate cancers and is also detected in cancers of the bladder and pancreas. This gene has a nonsynonymous nucleotide polymorphism at its start codon. This gene encodes a glycosylphosphatidylinositol-anchored cell membrane glycoprotein.

Function : May be involved in the regulation of cell proliferation. Has a cell-proliferation inhibition activity in vitro.
Subcellular Location : Cell membrane; Lipid-anchor, GPI-anchor.
Tissue Specificity : Highly expressed in prostate (basal, secretory and neuroendocrine epithelium cells).

抗體的生物素化標記實驗要點:
1. 干細胞抗原抗體品牌 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之間的分子比按蛋白質表面的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、異咪唑基及苯酚基,也可與糖基共價結合;
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合產生競爭作用;
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。
抗體的鑒定:
1)干細胞抗原抗體品牌 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,抗體分子的結合位點與抗原決定簇之間立體構型的合適度決定的。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。
