產(chǎn)品介紹 The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. This unit is responsible of the trypsin-like activity.The proteasome represents a large protein complex that exists inside all eukaryotes and archaea, and in some bacteria. The main function of proteasomes is to degrade unnecessary or damaged proteins by proteolysis. The most common form of the proteasome, known as the 26S Proteasome, contains one 20S Proteasome core particle structure and two 19S regulatory caps. The 20S Proteasome core is hollow and forms an enclosed cavity, where proteins are degraded, as well as openings at the two ends to allow the target protein to enter. The 20S Proteasome core particle contains many subunits, depending on the organism.

Function : The proteasome is a multicatalytic proteinase complex which is characterized by its ability to cleave peptides with Arg, Phe, Tyr, Leu, and Glu adjacent to the leaving group at neutral or slightly basic pH. The proteasome has an ATP-dependent proteolytic activity. This unit is responsible of the trypsin-like activity.

Subunit : The 26S proteasome consists of a 20S proteasome core and two 19S regulatory subunits. The 20S proteasome core is composed of 28 subunits that are arranged in four stacked rings, resulting in a barrel-shaped structure. The two end rings are each formed by seven alpha subunits, and the two central rings are each formed by seven beta subunits. The catalytic equivalent immune-specific subunit PSMB10. Interacts with -1 TAT protein.

Subcellular Location : Cytoplasm. Nucleus.

Tissue Specificity : Expressed at a low level in colonic mucosa. Up-regulated in colorectal cancer tissues.

Similarity : Belongs to the peptidase T1B family.

抗體的生物素化標記實驗要點：

1. 磷酸化蛋白酶體PSMβ7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(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）磷酸化蛋白酶體PSMβ7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?？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。抗體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。
