Validation:
Independent Antibody Validation in Cell lines (Figure 2) shows similar op18 expression profile in human, mouse and rat cell lines detected by two independent anti-op18 antibodies that recognize different epitopes, 4235 against C-terminus domain and 4237 against N-terminus domain. op18 proteins are detected in the most tested cell lines at different expression levels by the two independent antibodies.
Isoform: Human op18 has 2 isoforms, including isoform 1 (149aa, 17kD) and isoform 2 (174aa, 20kD) . Mouse op18 has one isoform (149aa, 17kD) and rat op18 also has one isoform (149aa, 17kD) . 4235 can detect only human isoform 1and it can also detect mouse and rat op18.

User Note: Optimal dilutions for each application to be determined by the researcher.
BACKGROUND: op18 Antibody: Op18 belongs to the stathmin family of genes and encodes a ubiquitous cytosolic phosphoprotein that may function as an intracellular relay integrating several signaling pathways such as those involved in cell proliferation and differentiation. Op18 has also been shown to be involved in the regulation of the microtubule filament system by destabilizing microtubules, thereby preventing assembly and promoting the disassembly of microtubules. More recently, op18 has been implicated as a potential target of the ASK1-p38 MAP kinase cascade, suggesting that the ASK1-p38 cascade may regulate microtubule dynamics through op18. Op18 is highly expressed in a wide variety of human malignancies, including leukemia, prostate cancer, ovarian carcinoma, and breast carcinoma, suggesting that op18 may be an ideal target for anti-cancer therapeutics.
