Name Chicken polyclonal antibody to human GFRa-2
Immunogen human GFRa-2
Immunogen Description Recombinant His-tagged human GFRα-2 protein produced using CHO-based Icosagen Cell factory Ltd. proprietary suspension cell line. For production of hGFRα-2, glycosylphosphatidyl-inositol GPI-anchor was removed and protein was secreted to the cell culture supernatant. Protein was purified by Ni-affinity chromatography following gel-filtration from cell culture supernatant

Background Glial cell line-derived neurotrophic factor (GDNF) and neurturin (NTN) are two structurally related, potent neurotrophic factors that play key roles in the control of neuron survival and differentiation. GFRa-2 is a member of the GDNF receptor family. It is a glycosylphosphatidyl-inositol(GPI)-linked cell surface receptor for both GDNF and NTN, and mediates activation of the RET tyrosine kinase receptor. This encoded protein acts preferentially as a receptor for NRTN compared to its other family member, GDNF family receptor alpha 1.

Figure 1. IF detection of human GFRα-2 expressed in U2OS cells. GFRα-2 was visualized using Chicken polyclonal antibody to human GFRα-2 (dilution 1:2000) and Goat anti-chicken IgY - H&L DyLight 550 (Abcam, ab96952) (dilution 1:200) as secondary antibody. For nuclear staining DAPI was used. ArrayScan VTI platform (Thermo Scientific) was used for image acquisition (10x objective). Composite picture was generated using pseudocolors green for GFRα-2 specific signal and blue for nuclei.

Figure 2. Western-Blot detection of human GFRα-2, using Chicken polyclonal antibody to human GFRα-2. GFRα-2 was C-terminally His tagged. Protein was expressed by CHO cell culture. 100 ng of purified protein was loaded per lane. Line 1. Prestained protein ladder (Naxo 8003). Line 2. hGFRα-2. Primary antibody dilution 1:5000 was used. Rabbit anti-chicken antibody (Icosagen)  was used as secondary antibody
