单克隆抗体这项新技术从根本上解决了在抗体制备中长期存在的特异性和可重复性问题，可用于探讨: ①蛋白质的精细结构；②淋巴细胞亚群的表面新抗原；③组织相容性抗原；④激素和药物的放射免疫（或酶免疫）分析；⑤肿瘤的定位和分类；⑥纯化微生物和寄生虫抗原；⑦免疫治疗和与药物结合的免疫-化学疗法 (“导弹”疗法,利用单克隆抗体与靶细胞特异性结合，将药物带至病灶部位.。
因此，单克隆抗体可直接用于人类疾病的诊断、预防、治疗以及免疫机制的研究，为人类恶性肿瘤的免疫诊断与免疫治疗开辟了广阔前景。
单克隆抗体结构相似且均一,有高度特异性
制备抗体都需要进行纯化处理
其次，察看次目的蛋白的存在形式，有没有多聚体形式及变构形式；
最后，查看多家抗体公司的DATA，看看别人的WB做出来的条带的位置。
根据你说的，特异识别多个组织中的同样大小的条带，我觉得很可能就是你的目的蛋白。
多抗，稀释度更大，特异性相对较差，容易出现多条带。
兔的单克隆抗体和鼠的单克隆抗体在使用上不会有什么区别。
用来很多抗体，许多时候觉得单抗多抗也未必是理论上那样的。单抗做不好的也有，多抗条带唯一且清晰的也有。
而且很多蛋白的抗体未必有那么多的选择。
