Immunoblotting for host proteins that are specifically associated with HIV-1 PIC. The proteins bound to the streptavidin magnetic beads after integration assay were probed with specific antibodies. SupT1-H9/HTLVIIIB represents HIV-1 infected cell samples, and SupT1-H9 represents non-infected control samples. The host proteins are indicated by accession names on the left. The 'NONO' is Non-POU domain-containing octamer-binding protein, 'NP1L1' is Nucleosome assembly protein 1-like 1 protein and 'CALR' is Calreticulin for which 8, 5 and 5 peptides were identified by MS analysis respectively. Beta-actin found in both samples is also shown.
