| 产品编号 | bs-13704R-BF405 |
| 英文名称 | Uroplakin Ia Rabbit pAb, BF405 conjugated |
| 中文名称 | BF405标记的尿路上皮特异蛋白1a抗体 |
| 英文别名 | UPK1A_HUMAN; Uroplakin-1a; UP1a; Tetraspanin-21; Tspan-21; Uroplakin Ia; UPIa; UPKa. |
| 产品应用 | IF=1:100-500 Not yet tested in other applications. |
| 抗体来源 | Rabbit |
| 免疫原 | KLH conjugated synthetic peptide derived from human Uroplakin Ia |
| 亚型 | IgG |
| 纯化方法 | affinity purified by Protein A |
| 克隆类型 | Polyclonal |
| 浓度 | 1mg/ml |
| 储存液 | 0.01M TBS (pH7.4) with 1% BSA, 0.02% Proclin300 and 50% Glycerol. |
| 亚基 | Homodimer; disulfide-linked. Interacts with uroplakin-2 (UPK2). |
| 亚细胞定位 | Membrane; Multi-pass membrane protein. |
| 组织特异性 | High expression restricted to ureteric urothelium (most superficial cells); low expression in prostate. Expression in normal urothelial cells is lost in culture. Some expression in tumor cell lines derived from urothelial malignancies. |
| 相似性 | Belongs to the tetraspanin (TM4SF) family. |
| 功能 | Component of the asymmetric unit membrane (AUM); a highly specialized biomembrane elaborated by terminally differentiated urothelial cells. May play an important role in normal bladder epithelial physiology, possibly in regulating membrane permeability of superficial umbrella cells or in stabilizing the apical membrane through AUM/cytoskeletal interactions. |
| 保存条件 | Shipped at 4℃. Store at -20℃ for one year. Avoid repeated freeze/thaw cycles. |
| 背景资料 | The asymmetric unit membrane (AUM) forms numerous plaques, which cover the apical surface of the urothelium. These plaques are thought to strengthen the urothelium and reduce the risk of rupturing during ladder distention. They are composed of four major integral membrane proteins called uroplakins (UP). The uroplakin family comprises UPIa, UPIb, UPII, and UPIII. Family members are conserved among several species, including human, mouse, rat, rabbit, dog, pig and sheep. UPIa and UPIb form tightly packed structures with UPII and UPIII, respectively. This pairing is required for normal urothelial plaque formation and is regulated by proteolytic processing of the uroplakin proteins. Uroplakins are expressed in normal urothelium and are used as specific markers of urothelial differentiation. They are also expressed in a majority of transitional cell carcinomas of the bladder (TCCs), which make the uroplakins a useful marker for detecting bladder cancer metastasis and for staging and monitoring chemotherapeutic response. |
