Figure 1. A comparison of purity and infectivity of rAAV vectors from different sources showing super purified and super infectious (close to clinical trial grade) rAAV vector prepared via our advanced double CsCl ultra-centrifugation approach. 
A. rAAV vectors (total 1E+9 VG per lane)  from different sources were resolved on SDS-PAGE followed by silver staining.  Lane 1: GMP manufactured rAAV vector from CHOP; Lane 2: rAAV prepared via our advanced 2xCsCl ultra-centrifugation approach; Lane 3: rAAV from Vector Core of BCM; Lane 4: rAAV from our competitor "V"; Lane 5: rAAV from our competitor "C"; Lane 6: Protein marker.
B. Super infectious rAAV vector prepared via advanced double CsCl ultra-centrifugation.  Left panel: rAAV9-GFP (total 5E+9 VG) from our competitor "V" injected to mouse eye; Right panel: rAAV-9-GFP (total 5E+9 VG) purified via advanced 2xCsCl ultra-centrifugation injected to mouse eye. 


Figure 2. A comparison of infectivity of rAAV vectors from different sources showing super purified rAAV prepared via advanced double CsCl ultra-centrifugation approach is super infectious.
rAAV1-GFP (total 2E+9 VG) from different sources were injected to mouse muscle tissue.  The GFP fluorescence was visualized 3 weeks post injection.  A. rAAV1-GFP from our competitor "V"; B. rAAV1-GFP from our pre-made rAAVs stock purified via advanced double CsCl ultra-centrifugation.  C. Quantification data showed that our super purified rAAV (bar 2) is ~ 9 times more infectious than that (bar 1) prepared via conventional CsCl ultra-centrifugation.  

* Final viral yield may depend on the nature of transgene.
