抗體的生物素化標記實驗要點:
1. Ras樣蛋白A抗體說明書 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*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。

產品介紹 Multifuntional GTPase involved in a variety of cellular processes including gene expression, cell migration, cell proliferation, oncogenic transformation and membrane trafficking. Accomplishes its multiple functions by interacting with distinct downstream effectors. Acts as a GTP sensor for GTP-dependent exocytosis of dense core vesicles. Plays a role in the early stages of cytokinesis and is required to tether the exocyst to the cytokinetic furrow. The RALA-exocyst complex regulates integrin-dependent membrane raft exocytosis and growth signaling. Key regulator of LPAR1 signaling and competes with ADRBK1 for binding to LPAR1 thus affecting the signaling properties of the receptor. Required for anchorage-independent proliferation of transformed cells.
Function : Multifunctional GTPase involved in a variety of cellular processes including gene expression, cell migration, cell proliferation, oncogenic transformation and membrane trafficking. Accomplishes its multiple functions by interacting with distinct downstream effectors. Acts as a GTP sensor for GTP-dependent exocytosis of dense core vesicles. Plays a role in the early stages of cytokinesis and is required to tether the exocyst to the cytokinetic furrow. The RALA-exocyst complex regulates integrin-dependent membrane raft exocytosis and growth signaling. Key regulator of LPAR1 signaling and competes with ADRBK1 for binding to LPAR1 thus affecting the signaling properties of the receptor. Required for anchorage-independent proliferation of transformed cells.
Subunit : Interacts with RALBP1 via its effector domain. Interacts with EXOC8 and EXOC2. EXOC2 and EXOC8 have overlapping binding sites and compete for RALA binding. Interacts with Clostridium exoenzyme C3. Interacts with RALGPS1. Interacts with LPAR1 and LPAR2. Interacts with ADRBK1 in response to LPAR1 activation. RALA and ADRBK1 mutually inhibit each other's binding to LPAR1.
Subcellular Location : Cell surface. Cell membrane; Lipid-anchor; Cytoplasmic side. Cleavage furrow. Midbody.
Post-translational modifications : Prenylation is essential for membrane localization. The geranylgeranylated form and the farnesylated mutant does not undergo alternative prenylation in response to geranylgeranyltransferase I inhibitors (GGTIs) and farnesyltransferase I inhibitors (FTIs).
Similarity : Belongs to the small GTPase superfamily. Ras family.
Database links : UniProtKB/Swiss-Prot: P11233.1
抗體的鑒定:
1)Ras樣蛋白A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,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。抗體的特異性高,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。
