乙酰基賴氨酸抗體，Anti-acetyl Lysine抗體 返回列表頁

背景介紹：In the nucleus, DNA is tightly packed into nucleosomes generating an environment which is highly repressive towards DNA processes such as transcription. Acetylation of lysine residues within proteins has emerged as an important mechanism used by cells to overcome this repression. The acetylation of non-histone proteins such as transcription factors, as well as histones appears to be involved in this process. Acetylation may result in structural transitions as well as specific signaling within discrete chromatin domains. The role of acetylation in intracellular signaling has been inferred from the binding of acetylated peptides by the conserved bromodomain. Furthermore, recent findings suggest that bromodomain/acetylated-lysine recognition can serve as a regulatory mechanism in protein-protein interactions in numerous cellular processes such as chromatin remodeling and transcriptional activation. The reversible lysine acetylation of histones and non-histone proteins plays a vital role in the regulation of many cellular processes including chromatin dynamics and transcription, gene silencing, cell cycle progression, apoptosis, differentiation, DNA replication, DNA repair, nuclear import, and neuronal repression. More than 20 acetyltransferases and 18 deacetylases have been identified so far, but the mechanistic details of substrate selection and site specificity of these enzymes remain unclear. Over 40 transcription factors and 30 other nuclear, cytoplasmic, bacterial, and viral proteins have been shown to be acetylated in vivo.

免疫組化結果的判斷

對免疫組化結果的判斷應持科學的慎重態度，要準確判斷陽性和陰性，排除假陽性和假陰性結果，必須嚴格對照實驗，對新發現的陽性結果，除有對照實驗結果之外，應進行多次重復實驗，可用幾種方法進行驗證。必須學會判斷特異性染色和非特異性染色，對初學者更為重要，否則會得出不科學的結論。特異性染色和非特異性染色的鑒別點主要在于特異性反應產物常分布于特定的部位。如胞漿內，也有分布在細胞核和細胞表面的，即具有結構性。特異性染色表現為在同一切片上呈現不同程度的陽性染色結果。非特異性染色表現為無一定的分布規律，常呈某一部位成片的均勻著色，細胞和周圍的結締組織均無區別的著色，或結締組織呈現很強的染色。非特異性染色常出現在干燥切片的邊緣，有刀痕或者折疊的部位。在過大的組織塊，中心固定不良也會導致非特異性染色。有時可見非特異性染色和特異性染色同時存在，由于過強的非特異性染色背景不但影響對特異性染色結果的觀察和記錄，而且令人對其特異性結果產生懷疑。

免疫組化的呈色深淺可反映抗原存在的數量，可作為定性、定位和定量的依據。
