General description

Monoclonal Anti-hnRNP-A2/B1 (mouse IgG2a isotype) is derived from the DP3B3 hybridoma produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice immunized with recombinant human hnRNP-A2. hnRNP-A2/B1 proteins are located in the nucleus of most tissues cells. However, the hnRNP-A2 protein is found also in the cytoplasm of skin and esophagus cells. In rat brain, hnRNP-A2/B1 proteins are found in neurons in the cerebral cortices, hippocampal formation, olfactory regions, caudate-putamin and the supraoptic nucleus of the hypothalamus.

Immunogen

recombinant human hnRNP-A2.

Application

Monoclonal Anti-hnRNP-A2/B1 antibody produced in mouse been used in :
  • enzyme linked immunosorbent assay (ELISA)
  • immunoblotting
  • immunoprecipitation
  • immunocytochemistry

Biochem/physiol Actions

In cells, it actively participates in pre-messenger RNA (pre-mRNA) processing, mRNA metabolism and transportation. It is overexpressed in the initial stage of lung cancer and in premalignant lesions. It also participates in neurodegeneration mediated by rCGG (repeats).

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, and 15 mM sodium azide.

Castration-resistant prostate cancer (CRPC) remains dependent on androgen receptor (AR) signaling. Alternative splicing of the AR to generate constitutively active, ligand-independent variants is one of the principal mechanisms that promote the development of resistance to next-generation antiandrogens such as enzalutamide.
