Ubiquitin D Antibody / Ubiquitin-Like Modifier Antibody [clone HID-21] (RQ4723)

Ubiquitin D Antibody Human and Mouse WB. Western blot analysis of Ubiquitin D expression was performed using anti-Ubiquitin D antibody in human and mouse cell and tissue lysates. Lane 1: HeLa. Lane 2: HepG2. Lane 3: Jurkat. Lane 4: MCF-7. Lane 5: SH-SY5Y. Lane 6: K562. Lane 7: mouse liver. Lane 8: mouse HEPA1/6. Ubiquitin D, also known as FAT10 (UBD), is a ubiquitin-like modifier that targets substrate proteins for proteasomal degradation and participates in immune regulation, inflammatory signaling, and cellular stress responses. A specific immunoreactive band is detected at approximately 23 kDa across all samples, consistent with the commonly observed migration of Ubiquitin D by western blot despite its predicted molecular weight of approximately 18 kDa. The broad expression profile demonstrates cross-species detection and supports the utility of Ubiquitin D Antibody for studies of ubiquitin-like protein conjugation, proteasomal degradation, immune signaling, and cancer biology.

Ubiquitin D Antibody Human HepG2 WB. Western blot analysis of Ubiquitin D expression was performed using anti-Ubiquitin D antibody in human HepG2 cell lysate. Ubiquitin D, also known as FAT10 (UBD), is a ubiquitin-like modifier that targets substrate proteins for proteasomal degradation and participates in immune regulation, inflammatory signaling, and cellular stress responses. A specific immunoreactive band is detected at approximately 18–22 kDa, corresponding to the expected molecular weight range of Ubiquitin D. Expression in HepG2 cells is consistent with the reported upregulation of FAT10 in hepatocellular carcinoma and its role in protein homeostasis and tumor biology. These results support the utility of Ubiquitin D Antibody for studies of ubiquitin-like protein conjugation, proteasomal degradation, immune signaling, and cancer research.
