Western blot analysis of STAT5 alpha in whole cell extracts of serum-starved HeLa cells treated with IFN-a (150ng/ml, 15 min) using a STAT5 alpha recombinant rabbit monoclonal antibody (Product # 701108) at a dilution of 2.5ug/ml. Samples were detected using chemiluminescence (ECL). Results show a band at ~90kDa.

ABfinity™ recombinant antibodies are rabbit monoclonal antibodies, unmatched for producing superior results. ABfinity™ antibodies are developed by immunizing animals, screening for functionality, cloning the immunogen-specific antibody genes into high-level mammalian expression vectors, produced on a large scale, and purified with Protein A.
ABfinity™ monoclonal antibodies resemble rabbit monoclonals isolated from serum or produced by hybridomas, but demonstrate greater specificity and sensitivity. Because ABfinity™ recombinant antibodies are derived from cloned DNA sequences of the heavy and light antibody chains, they are not susceptible to cell-line drift or lot-to-lot variation, thus allowing for peak specificity and performance.
Intact IgG appears on a non-reducing gel as ~150 kDa band and upon reduction generating a ~25 kDa light chain band and a ~50 kDa heavy chain.
STAT5, consisting of isoform a and b, belongs to the family of STAT (signal transducers and activators of transcription) proteins which are phosphorylated by receptor associated kinases, translocate to the nucleus, and act as transcription factors in response to cytokines and growth factors. STAT5a is activated by IL2, IL3, IL7, GM-CSF, erythropoietin, thrombopoietin, and various growth hormones. In humans, the STAT5a gene is located on chromosome 17.
