英文名稱：Anti-Cryptochrome 1 antibody

隱花色素蛋白1抗體背景介紹：Circadian clocks are biological timepieces that regulate hormonal rhythms, sleep cycles and feeding behaviors. These rhythms are generated in the superchiasmatic nucleus (SCN), a cell-autonomous circadian oscillator located within the brain that is synchronized with the environment by light. A number of transcription factors, including Clock and BMAL1, are molecular components of the SCN that induce the expression of proteins involved in light/dark cycle entrainment, which include Per1 and Per2. Tim, for timeless, generates a negative feedback loop that regulates the activity of Clock by suppressing the expression of Clock target genes. Tim forms heterodimers with Per1 and Per2 that bind Clock and block the activation of Clock-BMAL1 dimers to repress Per gene expression. Additionally, the CRY proteins, which are cryptochrome photoreceptors for the circadian clock, function as light-independent inhibitors of the circadian clock. CRY1 and CRY2 negatively regulate SCN components by associating with the activators Clock-BMAL1, and also with the various feedback inhibitors Per1, Per2 and Tim.

隱花色素蛋白1抗體,Anti-Cryptochrome 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。

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）切片在染色過程中抗體過濃，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)間過長(zhǎng)；（4）抗體溫育的時(shí)間過長(zhǎng)；（5）H2O2濃度過高，呈色速度過快；（6）粘附劑太厚。

3.所有切片背景過深：（1）未用酶消化處理切片；（2）切片或涂片過厚；（3）漂洗不夠；（4）底物呈色反應(yīng)過久；（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)。
