重組抗體

重組抗體,也稱為基因工程抗體,是指通過DNA重組技術將抗體相應的基因序列根據需要進行改造和重組,并構建在質粒上,再通過蛋白外源表達技術將構建好的質粒轉染/轉化入適合的宿主細胞表達獲得的抗體。換言之,重組抗體是通過將免疫特異性重鏈和輕鏈抗體克隆到高產的哺乳動物表達載體中而制成的。將得到的載體引入到表達宿主(如細菌、酵母或哺乳動物)中,用于生產高質量的功能性抗體。重組抗體很好的解決了動物源抗體引起的人體排斥反應,使得抗體實現人源化,使抗體的效能更為完善。
近年來,重組抗體的使用在治療和診斷中變得越來越廣泛。 與傳統抗體相比具有顯著優勢,重組抗體變得越來越受青睞。最重要的一點是重組抗體可以最大化人源化以解決不同物種之間的異質性。
重組抗體可分為五大類:嵌合抗體、人源化抗體、全人源化抗體、小分子抗體、雙特異性抗體。華美生物擁有近700種重組兔單克隆抗體,具有高純度、親和力強以及批次間偏差小等特點。

關于重組抗體
與傳統抗體相比,重組抗體的優勢具體如下:
- 更高的一致性和重復性
因為重組抗體是由一組獨特的基因發展而來的,所以抗體生產是可控且可靠的??梢员苊怆s交瘤細胞制備中的一些問題,如基因丟失、基因突變和細胞株漂移等。這使得抗體的批次間差異非常小,從而為您提供高度可重復的結果。
- 更高的靈敏度和特異性
利用重組技術,更容易通過抗體工程提高抗體特異性和靈敏度。所需克隆的選擇過程發生在雜交瘤細胞和重組克隆階段,這使我們能夠選擇最優的抗體質量。
- 易于擴展
隨著抗體基因的分離,與傳統單克隆技術相比,抗體表達能夠以任何規模在更短的時間內進行。這意味著我們可以在數周而非數月內產生定制抗體。
- 無動物高通量生產
一旦分離出產生抗體的基因,就可以實現無動物體外生產。
