細(xì)胞生長調(diào)節(jié)核仁蛋白抗體，Anti-LYAR抗體簡單介紹：

產(chǎn)品編號：BYK-18456R

英文名稱：Anti-LYAR
中文名稱：細(xì)胞生長調(diào)節(jié)核仁蛋白抗體

別名：Cell growth regulating nucleolar protein; Cell growth-regulating nucleolar protein; Likely ortholog of mouse Ly1; reactive clone; Ly1; reactive; Ly1; reactive homolog (mouse); Ly1; reactive homolog; LYAR; LYAR_HUMAN; ZC2HC2; ZLYAR.   

背景介紹：LYAR is a 379 amino acid nucleolar protein containing two C2HC-type zinc fingers. Expressed at high levels in immature spermatocytes, early embryos and in fetal liver and thymus with low expression in kidney and spleen, LYAR may function as a novel nucleolar oncoprotein to regulate cell growth. It is suggested that LYAR participates in regulating the stability of C23, a protein that is critical for maintaining the self-renewal and differentiation of embryonic stem cells (ESCs). C23 is a eukaryotic nucleolar phosphoprotein that influences synthesis and maturation of ribosomes. LYAR forms a complex with C23, thereby preventing self-cleavage and maintaining steady levels of C23 in undifferentiated ESCs. Downregulation of LYAR decreases C23 stability in ESCs, which in turn negatively affects growth and increases the rate of apoptosis of these cells.

合適的抗體稀釋度

抗體的濃度是免疫染色的關(guān)鍵，如果抗體濃度過高，抗體分子過多于抗原決定簇，可導(dǎo)致抗體結(jié)合減少，產(chǎn)生陰性結(jié)果。此陰性結(jié)果并不一定是缺少抗原，而是由于抗體過量，這種現(xiàn)象類似于凝集反應(yīng)中的前帶效應(yīng)（prozone effect）。因此，必須使用一系列稀釋做“棋盤式效價滴定”，檢測抗體的合適稀釋度，以得到zui大強(qiáng)度的特異性染色和zui弱的背景染色。抗體稀釋度應(yīng)根據(jù)：1.抗體效價高，溶液中特異性抗體濃度越高，工作稀釋度越高；2.一般講，應(yīng)用的抗體稀釋度越大，溫育時間越長；3.對于抗體與非特異性蛋白的結(jié)合，只有高稀釋度時才能防止其非特異性背景染色；4.稀釋用緩沖液的種類，標(biāo)本的固定和處理過程等也可影響稀釋度，所以合適的稀釋度應(yīng)根據(jù)具體情況測定。抗體的稀釋主要是指*抗體，因?yàn)?抗體中特異性抗體合適的濃度是關(guān)鍵，應(yīng)用高稀釋度*抗體僅高親和力的特異性染色反應(yīng)，減少或消除其中交叉抗體反應(yīng)。
