Technical Data
GFR alpha3, IN (Glycosylphosphadidylinositol linked Protein, GDNFRg, Ret ligand 3, RETL3)
Members of the glial cell line-derived neurotrophic factor (GDNF) family including GDNF and neurturin (NTN) play essential roles in the control of vertebrate neuron survival and differentiation. A new member of the GDNF family was recently identified and designated persephin (1). Physiological responses to these neurotrophic factors require two receptor subunits, the novel glycosylphosphadidylinositol linked protein GFRa and Ret receptor tyrosine kinase GFRb (2). Following the findings of GFRa-1 and -2, a novel receptor in GFRa family was identified very recently from human and mouse and designated GFRa-3 (3-7). GFRa-3 binds persephin, thus, persephin, GFRa-3, and Ret PTK form a complex to transduce persephin signal and to mediate persephin function.

Suitable for use in Western Blot. Other applications not tested.

Recommended Dilution:
Western Blot: 1:500 to 1:1,000
Optimal dilutions to be determined by the researcher.

Antibody blocking peptide: G2033-50P

Positive Control:
Murine kidney, liver or heart tissue lysates.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20C or colder. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
