Fig. 4From: rs2013278 in the multiple immunological-trait susceptibility locus CD28 regulates the production of non-functional splicing isoformsProtein expression of each CD28 splicing isoform product. Expression of GFP-conjugated CD28 isoforms was analyzed using an anti-GFP antibody. The protein product of CD28Δex2 was not detectedBack to article page
