Product Overview
Clone 18H23 is a rabbit monoclonal antibody that recognizes high mobility group protein HMG-I/HMG-Y (gene HMGA1) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF and flow cytometry. The predicted molecular weight is 11.7 kDa, and the supplier reports an observed band at about 17 kDa.
HMGA1 (HMG-I/HMG-Y) is a small architectural chromatin protein that uses AT-hook motifs to bind the minor groove of AT-rich DNA. By bending DNA and helping assemble transcription factor complexes it tunes the activity of many genes. It is abundant in embryonic cells and many tumors, so it is studied in development and cancer.

Immunogen
Synthetic peptide based on the sequence of human HMGA1.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places high mobility group protein HMG-I/HMG-Y in the nucleus and chromosome. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
