Specificity / Sensitivity

HMGA1 (D4F8) Rabbit mAb recognizes endogenous levels of total HMGA1 protein, isoforms 1a and 1b. Based on sequence homology, this antibody is not predicted to cross-react with HMGA2.

Species Reactivity:

Human, Monkey

Species predicted to react based on 100% sequence homology

Bovine

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly68 of human HMGA1 protein.

Background

HMGA1, formerly known as HMG-I/Y, belongs to a family of high mobility group proteins that contain an AT-hook DNA binding domain. HMGA proteins are considered architectural transcription factors; they do not have direct transcriptional activation capacity, but instead regulate gene expression by changing DNA conformation through binding to AT-rich regions in the DNA and/or direct interaction with other transcription factors (1,2). HMGA1 is highly expressed during embryogenesis and in embryonic stem cells, but not in fully differentiated adult tissues (2-4). Research studies have shown that HMGA1 is over-expressed in rapidly dividing neoplastic cells and a wide variety of aggressive cancers, including thyroid, colon, breast, pancreas, and prostate (2-4). Investigators have shown that forced expression of HMGA1 induces cellular transformation and an epithelial-to-mesenchymal transition (EMT), while inhibition of HMGA1 expression blocks anchorage-independent cell growth and proliferation of cancer cells, suggesting that HMGA1 contributes to carcinogenesis by inducing and maintaining a de-differentiated, highly proliferative cell state (5-8).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
