GFP, or green fluorescent protein, is a chemiluminescent protein derived from Aequorea jellyfish that was first discovered by Osamu Shimomura.  It was soon after established that the emission spectra of GFP was right around 509nm, or the ultraviolet color range.  The GFP gene is often used to form expression constructs in order to closely follow protein behavior, cellular differentiation, protein localization and more.  The following articles employed a GFP antibody in conjunction with various other GFP construct techniques to strengthe

SOX9 is a member of the SOX family of HMG DNA-binding domain transcription factors. The protein encoded by this gene recognizes the sequence CCTTGAG along with other members of the HMG-box class DNA-binding proteins. cAMP and protein kinase A (PKA) stimulation appear to induce SOX-9 nuclear translocation through its nuclear import upon phosphorylation at two particular serine residues.   It is required for the development and differentiation of multiple cell lineages and is expressed in primary and recurrent prostate cancers.

The Hypoxia-inducible Factor 1 (HIF1) protein is a heterodimeric transcription factor which plays an important role in mammalian oxygen homeostasis in conditions of hypoxia, or low oxygen concentration. HIF-1 alpha antibody reagents are widely used in disease research, as hypoxia is known to contribute to many diseases including cancer, pulmonary hypertension and congenital heart disease. We at Novus Biologicals are one of the leading antibody suppliers of HIF-1 products.
