產(chǎn)品介紹：Alpha 1 Fetoprotein is a major plasma protein produced by the yolk sac and the liver during fetal life. Alpha fetoprotein expression in adults is often associated with hepatoma or teratoma. However, hereditary persistance of alpha-fetoprotein may also be found in individuals with no obvious pathology. The protein is thought to be the fetal counterpart of serum albumin, and the alpha fetoprotein and albumin genes are present in tandem in the same transcriptional orientation on chromosome 4. Alpha fetoprotein is found in monomeric as well as dimeric and trimeric forms, and binds copper, nickel, fatty acids and bilirubin. The level of alpha fetoprotein in amniotic fluid is used to measure renal loss of protein to screen for spina bifida and anencephaly. Expression has been documented in human adrenal, liver, ovary, testis, and pancreas. ESTs have been isolated from normal human brain, liver/spleen, embryo and uterus tissue libraries.
抗體的多樣性：
抗體的異質(zhì)性。抗體的組成極為復(fù)雜，是由成千上萬、多種多樣的免疫球蛋白（Ig）分子所組成。這些Ig分子在形狀、大小、結(jié)構(gòu)以及氨基酸的組成和排列上，既相似，又有差別。由于有差別，它們的電泳活性就有很大的變化。

因?yàn)榭贵w具有與抗原決定簇相對(duì)應(yīng)的結(jié)合部位（抗原結(jié)合簇），所以抗體與抗原的結(jié)合具有特異性。另一方面，抗體本身是一種蛋白質(zhì)，具有本身的氨基酸組成、排列和立體結(jié)構(gòu)，對(duì)異種動(dòng)物來說，它又是抗原。各類Ig都具有可用血清學(xué)方法檢出的抗原特異性，它們表現(xiàn)出不同的血清學(xué)類型。

免疫熒光技術(shù)的實(shí)驗(yàn)步驟：

一、準(zhǔn)備好試劑與儀器：

磷酸鹽緩沖鹽水、熒光標(biāo)記的抗體溶液、緩沖甘油、搪瓷桶三只、有蓋搪瓷盒一只、熒光顯微鏡、玻片架、濾紙、37℃溫箱等。

二、實(shí)驗(yàn)步驟

1.滴加0.01mol/L，pH7.4的PBS于待檢標(biāo)本片上，十分鐘后棄去，使標(biāo)本保持一定濕度。

2.滴加適當(dāng)稀釋的熒光標(biāo)記的抗體溶液，使其覆蓋標(biāo)本，置于有蓋搪瓷盒內(nèi)，保溫一定時(shí)間以三十分鐘為參考。

3.取出玻片，置玻片架上，先用0.01mol/L，pH7.4的PBS沖洗后，再按順序過0.01mol/L，pH7.4的PBS三缸浸泡，每缸三到五分鐘，并不停地?fù)u晃振蕩。

4.取出玻片，用濾紙吸去多余水分，但不使標(biāo)本干燥，加一滴緩沖甘油，以蓋玻片覆蓋。

5.立即用熒光顯微鏡觀察。觀察標(biāo)本的特異性熒光強(qiáng)度。
