核糖核酸結合蛋白2抗體背景介紹:PTBP-2 is a member of the polypyrimidine tract binding family of proteins. Predominantly expressed in brain, but also found in heart and skeletal muscle, PTBP-2 localizes to the nucleus and contains four RRM (RNA recognition motif) domains. PTBP-2 functions as an RNA-binding protein associated in a complex that is involved in the regulation of exon splicing and the stabilization of mRNAs in the cytoplasm. Six isoforms exist for PTBP-2 due to alternative splicing events. Isoforms 1 and 2 (also known as nPTB1 and nPTB2/PTBPLP-L, respectively) are neuronal-specific. Isoforms 3 and 4 (also known as nPTB3/PTBPLP-L and nPTB4, respectively) are found in non-neuronal tissues, as are isoforms 5 and 6 (also known as nPTB5/nPTB7/PTBPLP-S and nPTB6/nPTB8/PTBPLP-S, respectively). The existence of various isoforms may function to modulate the RNA-binding properties of PTBP-2

抗體修復方式
修復液:0.01M 枸櫞酸(pH6.0)或者0.05M EDTA(pH8.0)
核糖核酸結合蛋白2抗體,Anti-PTBP2抗體抗原修復,必須注意以下問題:
1、修復液的選擇。
0.01M枸櫞酸(pH6.0):應用zui多的抗原修復液,適用于大多數(shù)的抗原,用該液修復后的抗原表達增強,抗原的定性和定位很理想,結果不錯;
0.05M EDTA(pH8.0):應用較多的抗原修復液,修復能力較強,對于保存時間較長的切片或目的蛋白表達較弱的組織有很好的修復效果,需要控制好修復時間,否則容易出現(xiàn)較重的背景;
0.01M TBS(pH7.4):中性修復液,適用于大多數(shù)抗原,對于核定位蛋白有較好的修復效果;
*:應用較多的抗原修復液,適用于大多數(shù)的抗原,使用溫度37℃,對于容易脫片的切片有很好的保護作用。
*:應用較多的抗原修復液,適用于大多數(shù)的抗原
2.抗原熱修復時應選擇的溫度。
據(jù)實驗認為溫度在92℃-98℃是合適的,尤其在95℃為,這是因為:(1)這種溫度未達沸騰,切片不容易脫離載玻片;(2)能夠解離和破壞與蛋白交聯(lián)的甲醛醛鍵等,處理時可以隨意選擇和確定抗原修復的作用時間。如果選擇高壓修復,因為溫度較高,時間不宜過長
3.抗原修復時有效溫度所需持續(xù)時間根據(jù)各單位的設備條件以及使用的儀器不同,抗原修復時在有效的溫度范圍內所持續(xù)的時間也不一樣。
4.抗原修復液必須遵循自然降溫規(guī)律,否則效果不好或達不到抗原修復的目的。
5.盡量使用足量的抗原修復液,防止切片干涸。
6.切片必須附貼牢固,否則發(fā)生掉片。
