Chicken polyclonal antibody to human GFRa-4


Datasheet as
Name Chickenpolyclonal antibody to human GFRa-4
Immunogen human GFRa-4
Immunogen Description Recombinant His-tagged human GFRa-4 protein produced using CHO-based Icosagen Cell factory Ltd. proprietary suspension cell line. For production of hGFRa-4, 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

Figure 1. IF detection of human GFRα-4 expressed in U2OS cells. GFRα-4 was visualized using Chicken polyclonal antibody to human GFRα-4 (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-4 specific signal and blue for nuclei

Figure 2. Western-Blot detection of human GFRα-4, using Chicken polyclonal antibody to human GFRα-4. Protein was expressed by CHO cell culture. 100 ng of purified protein was loaded per lane. Line 1. hGFRα-4. Primary antibody dilution 1:5000 was used. Line 2. Prestained protein ladder (Naxo 8003). Rabbit anti-chicken antibody, HRP conjugate (903-100, Icosagen) was used as secondary antibody
