產(chǎn)品介紹 The NFKB complex consists of NFKB1 or NFKB2 bound to REL, RELA, or RELB. The NFKB complex is inhibited by I kappa B proteins (NFKBIA, or NFKBIB), which inactivate NF kappa B by trapping it in the cytoplasm. Phosphorylation of serine residues on the I kappa B proteins by kinases (IKBKA, or IKBKB,) marks them for destruction via the ubiquitination pathway, thereby allowing activation of the NF kappa B complex.

Function : NF-kappa-B is a pleiotropic transcription factor which is present in almost all cell types and is involved in many biological processed such as inflammation, immunity, differentiation, cell growth, tumorigenesis and apoptosis. NF-kappa-B is a homo- or heterodimeric complex formed by the Rel-like domain-containing proteins RELA/p65, RELB, NFKB1/p105, NFKB1/p50, REL and NFKB2/p52. The dimers bind at kappa-B sites in the DNA of their target genes and the individual dimers have distinct preferences for different kappa-B sites that they can bind with distinguishable affinity and specificity. Different dimer combinations act as transcriptional activators or repressors, respectively. NF-kappa-B is controlled by various mechanisms of post-translational modification and subcellular compartmentalization as well as by interactions with other cofactors or corepressors. NF-kappa-B complexes are held in the cytoplasm in an inactive state complexed with members of the NF-kappa-B inhibitor (I-kappa-B) family. In a conventional activation pathway, I-kappa-B is phosphorylated by I-kappa-B kinases (IKKs) in response to different activators, subsequently degraded thus liberating the active NF-kappa-B complex which translocates to the nucleus. NF-kappa-B heterodimeric RelB-p50 and RelB-p52 complexes are transcriptional activators. RELB neither associates with DNA nor with RELA/p65 or REL. Stimulates promoter activity in the presence of NFKB2/p49. As a member of the NUPR1/RELB/IER3 survival pathway, may provide pancreatic ductal adenocarcinoma with remarkable resistance to cell stress, such as starvation or gemcitabine treatment.

Subunit : Component of the NF-kappa-B RelB-p50 complex. Component of the NF-kappa-B RelB-p52 complex. Self-associates; the interaction seems to be transient and may prevent degradation allowing for heterodimer formation with p50 or p52. Interacts with NFKB1/p50, NFKB2/p52 and NFKB2/p100. Interacts with NFKBID.

Subcellular Location : Nucleus. Cytoplasm, cytoskeleton, centrosome. Note=Co-localizes with NEK6 in the centrosome.

Post-translational modifications : Phosphorylation at 'Thr-103' and 'Ser-573' is followed by proteasomal degradation.

Similarity : Contains 1 RHD (Rel-like) domain.

抗體的生物素化標記實驗要點：

1. 轉(zhuǎn)錄因子RelB蛋白抗體費用 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(zhì)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(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(jié)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(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,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(jié)合產(chǎn)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）轉(zhuǎn)錄因子RelB蛋白抗體費用 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(zhì)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(jié)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(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。
