中文名稱：羧肽酶X(M14家族1)抗體

英文名稱：Anti-CPXM antibody

羧肽酶X(M14家族1)抗體,Anti-CPXM抗體背景介紹：CPXM (carboxypeptidase X, member 1) belongs to the peptidase M14 family. However, no carboxypeptidase activity has yet been detected. It may be involved in cell-cell interactions.Members of the M14 metallocarboxypeptidase protein family serve many diverse functions and are divided into three subfamilies based on structure, function and amino acid sequence similarity. Belonging to the N/E subfamily, CPXM (metallocarboxypeptidase CPX-1) is a 734 amino acid protein that contains a F5/8 type C domain and likely binds one zinc ion per subunit. Most members of the N/E subfamily contain several domains, including an active carboxypeptidase domain and signal peptide, and are thought to function mostly in protein-protein interactions and/or protein-membrane interactions, thereby targeting the protein to specific locations within the secretory pathway. CPXM is a unique member of this subfamily in that it does not appear to exhibit any enzymatic activity due to lack of several active-site residues that are present in the catalytic domain of other members of the N/E subfamily. Studies showing that CPXM expression is regulated during osteoclastogenesis suggest that CPXM may play a role in osteoclast differentiation. There are two isoforms of CPXM which are a result of alternative splicing events.

羧肽酶X(M14家族1)抗體抗原抗體反應(yīng)：
一、抗原抗體反應(yīng)特點(diǎn)
1.高度特異性，特異性是抗原抗體反應(yīng)的zui主要特征，特定抗原決定簇只與特定抗體結(jié)合；
2.可逆性:抗原與抗體結(jié)合形成抗原抗體復(fù)合物的過(guò)程是一種動(dòng)態(tài)平衡, 其反應(yīng)式為：Ag+AbAg·Ab；
3.適當(dāng)濃度和比例；
4.敏感性:在測(cè)定血清中某一物質(zhì)的含量時(shí)，化學(xué)比色法的敏感度為mg/ml水平，酶反應(yīng)測(cè)定法的敏感度約為5~10μg/ml，免疫測(cè)定中凝膠擴(kuò)散法的敏感度與酶反應(yīng)法相仿。
二、影響抗原抗體反應(yīng)的因素
1.電解質(zhì) ：抗原抗體特異結(jié)合后，膠體粒便可發(fā)生脫水作用，此時(shí)易受電解質(zhì)影響，如有適當(dāng)濃度的電解質(zhì)存在就會(huì)使它們失去部分負(fù)電荷而相互凝聚，于是出現(xiàn)明顯的凝集或沉淀現(xiàn)象。
2.酸堿度:合適的pH為6-8。
3.溫度:37℃通常是抗原體反應(yīng)zui適溫度。

羧肽酶X(M14家族1)抗體,Anti-CPXM抗體免疫組化染色失敗的幾種原因

1.所染的全部切片均為陰性結(jié)果，包括陽(yáng)性對(duì)照在內(nèi)，全部呈陰性反應(yīng)，原因可能是：（1）染色未按嚴(yán)格操作步驟進(jìn)行；（2）漏加一種抗體，或抗體失效；（3）緩沖液內(nèi)含*，抑制了酶的活性；（4）底物中所加H2O2量少或失效；復(fù)染或脫水劑使用不當(dāng)。

2.所有切片均呈弱陽(yáng)性反應(yīng)：（1）切片在染色過(guò)程中抗體過(guò)濃，或干燥了；（2）緩沖液配制中未加氯化鈉或pH不準(zhǔn)確，洗滌不*；（3）使用已變色的呈色底物溶液，或呈色反應(yīng)時(shí)間過(guò)長(zhǎng)；（4）抗體溫育的時(shí)間過(guò)長(zhǎng)；（5）H2O2濃度過(guò)高，呈色速度過(guò)快；（6）粘附劑太厚。

3.所有切片背景過(guò)深：（1）未用酶消化處理切片；（2）切片或涂片過(guò)厚；（3）漂洗不夠；（4）底物呈色反應(yīng)過(guò)久；（5）蛋白質(zhì)封閉不夠或所用血清溶血；（6）使用全血清抗體稀釋不夠。

4.陽(yáng)性對(duì)照染色良好，檢測(cè)的陽(yáng)性標(biāo)本呈陰性反應(yīng)，固定和處理不當(dāng)是zui常見(jiàn)的原因。對(duì)于陽(yáng)性結(jié)果的定量判斷，常規(guī)方法是根據(jù)呈色深淺和陽(yáng)性細(xì)胞數(shù)量分類計(jì)數(shù)，以（-）、+、++、+++等分級(jí)和計(jì)數(shù)統(tǒng)計(jì)。
