產品介紹：The protein encoded by this gene is a lysosomal cysteine proteinase that plays a major role in intracellular protein catabolism. Its substrates include collagen and elastin, as well as alpha-1 protease inhibitor, a major controlling element of neutrophil elastase activity. The encoded protein has been implicated in several pathologic processes, including myofibril necrosis in myopathies and in myocardial ischemia, and in the renal tubular response to proteinuria. This protein, which is a member of the peptidase C1 family, is a dimer composed of disulfide-linked heavy and light chains, both produced from a single protein precursor. At least two transcript variants encoding the same protein have been found for this gene.
抗體的多樣性：
抗體的異質性。抗體的組成極為復雜，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、結構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。

因為抗體具有與抗原決定簇相對應的結合部位（抗原結合簇），所以抗體與抗原的結合具有特異性。另一方面，抗體本身是一種蛋白質，具有本身的氨基酸組成、排列和立體結構，對異種動物來說，它又是抗原。各類Ig都具有可用血清學方法檢出的抗原特異性，它們表現出不同的血清學類型。

免疫熒光技術的實驗步驟：

一、準備好試劑與儀器：

磷酸鹽緩沖鹽水、熒光標記的抗體溶液、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、實驗步驟

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

2.滴加適當稀釋的熒光標記的抗體溶液，使其覆蓋標本，置于有蓋搪瓷盒內，保溫一定時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，并不停地搖晃振蕩。

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

5.立即用熒光顯微鏡觀察。觀察標本的特異性熒光強度。
