Product Overview
Mitogen-activated protein kinase (MAPK) signaling cascades include MAPK or extracellular signal-regulated kinase (ERK), MAPK kinase (MKK or MEK), and MAPK kinase kinase (MAPKKK or MEKK). MAPKK kinase/MEKK phosphorylates and activates its downstream protein kinase, MAPK kinase/MEK, which in turn activates MAPK. The kinases of these signaling cascades are highly conserved, and homologs exist in yeast, Drosophila, and mammalian cells. MAPKKK5 contains 1,374 amino acids with all 11 kinase subdomains. Northern blot analysis shows that MAPKKK5 transcript is abundantly expressed in human heart and pancreas. The MAPKKK5 protein phosphorylates and activates MKK4 (aliases SERK1, MAPKK4) in vitro, and activates c-Jun N-terminal kinase (JNK)/stress-activated protein kinase (SAPK) during transient expression in COS and 293 cells; MAPKKK5 does not activate MAPK/ERK.

The recommended starting dilution for Western Blot is WB 1:500-1:1000. Optimal dilution should be determined empirically for each laboratory setup, sample type, and detection system. Use freshly prepared lysates with protease inhibitors; add phosphatase inhibitors if studying phosphorylation-dependent forms of ASK1. Expected band size: Calculated 155kDa, Observed 155kDa. If background is high, increase blocking (5% non-fat milk or BSA in TBST) and/or increase wash stringency.
This antibody has been experimentally validated in: Human. Cross-reactivity with other species has not been systematically evaluated. If your sample species is not listed, assess immunogen sequence homology to your target species ortholog. The immunogen used is: "A synthetic peptide of human ASK1" — higher sequence identity between species increases the probability of cross-reactivity, but experimental validation with appropriate controls is necessary before drawing scientific conclusions.
Store at -20℃ Valid for 12 months. Avoid freeze / thaw cycles. Storage Buffer: 50mM Tris-Glycine(pH 7.4), 0.15M NaCl, 40% Glycerol, 0.01% Sodium azide and 0.05% protective protein. To maintain antibody activity, avoid repeated freeze-thaw cycles. Aliquot into single-use volumes before first freeze. If working with the antibody frequently, keep a working stock at 4°C for up to 4 weeks — add 0.02% sodium azide to the working stock as a bacteriostatic agent if azide is not already present in the buffer. Monitor performance against a validated positive control when transitioning between storage aliquots or lots.
This monoclonal antibody (clone R06-4F5) provides highly consistent, epitope-specific recognition of ASK1, making it ideal for quantitative assays, multiplex panels, and studies requiring strict reproducibility across experiments and independent laboratories. Unlike polyclonal preparations, each production batch from a single hybridoma clone generates antibody with identical epitope specificity, affinity, and isotype — ensuring reliable signal comparison in longitudinal studies or multi-site collaborations. When citing this antibody in publications, include the clone designation (clone R06-4F5) to enable third-party reproducibility verification.
Customization & Add-ons: Can't find the antibody you need—or require a custom format for your assay? We can help you source the best match or support custom antibody solutions for diverse research needs, including species and isotype selection, conjugations and labeling (e.g., HRP/AP, biotin, fluorophores), purification grade options (Protein A/G, affinity purified), formulation preferences (buffer selection, carrier-free, glycerol-free), custom concentrations and aliquoting, low-endotoxin options for cell-based work, and application-focused QC/validation support (project dependent).
