Product Overview
This rabbit polyclonal antibody recognizes CDK-activating kinase assembly factor MAT1 (gene MNAT1) in human, mouse and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 35.8 kDa, and the supplier reports an observed band at about 35 kDa.
MAT1 (MNAT1) is the assembly factor of the CDK-activating kinase (CAK), which also contains CDK7 and cyclin H. CAK activates cell cycle kinases such as CDK1, CDK2, CDK4 and CDK6, and as part of the transcription factor TFIIH it phosphorylates RNA polymerase II, linking MAT1 to both cell cycle control and transcription.

Immunogen
Recombinant human MNAT1 fragment (Met1–Ser309), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places CDK-activating kinase assembly factor MAT1 in the nucleus. Tissue expression noted by UniProt (human): Highest levels in colon and testis. The samples tested by the supplier (listed above) are a practical starting point for positive controls.

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).
