Scientific Data Images for Human ASK1 Antibody

Detection of Human ASK1 antibody by Western Blot.

Detection of Human ASK1 by Western Blot.

Western blot shows lysates of Raji human Burkitt's lymphoma cell line. PVDF membrane was probed with 1 µg/mL of Sheep Anti-Human ASK1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3575) followed by HRP-conjugated Anti-Sheep IgG Secondary Antibody (Catalog # HAF016). A specific band was detected for ASK1 at approximately 154 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.

Detection of Human ASK1 by Western Blot

M. tb virulence induces ASK1 expression. Human MDMs were obtained after seven days in culture. 2 × 106 MDMs were infected at MOI 1 and MOI 10 with an avirulent (H37Ra) and MOI 1 and MOI 5 with a virulent (H37Rv) strain of M. tb; 2 × 106 MDMs were not infected as a control (Uninf). At 24 h postinfection, cells were recovered and prepared for Western Blot. Representative Western blot of ASK1, JNK1, JNK2, p-p38, and GAPDH (a). Band densities of ASK1 (b), JNK1 (c), JNK2 (d), and p-p38 (e) were normalized against GAPDH and quantified by densitometry analysis with the ImageJ software. Results are shown in relative units (RU) of concentration. The bar graphs show the mean ± SD from two independent experiments (n = 2 donors and two technical replicates). Statistical analysis was performed using Kruskal–Wallis analysis, followed by Dunn’s post hoc test. * p < 0.05.

Background: ASK1

Apoptosis signal-regulating kinase 1 (ASK1) is a MAP kinase kinase kinase also known as MEKK5 and MAP3K5. ASK1 is induced by inflammatory cytokines, UV light, and other stress-related stimuli to phosphorylate MAP kinase kinases that in turn activate the p38 and JNK families of MAP kinases. Mice lacking ASK1 are resistant to stress-induced p38 and JNK activation and cell death.

Long Name

Apoptosis Signal-regulated Kinase 1

Alternate Names

MAP3K5, MEKK5
