Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/5000) and Loading control antibody (Beta Actin, HY-P80993, 1/10,000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Rabbit IgG-HRP Secondary Antibody (HY-P8001 ,1/10,000) was used for 1 hour at room temperature.

Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 in PBS for 15 minutes at room temperature, then blocked with quick block buffer for 10 minutes at room temperature. Cells were then incubated with IκB-α Antibody (HY-P86197) at 1/300 dilution in quick block buffer overnight at 4 ℃. AF488-conjugated Goat Anti-Rabbit IgG H&L (HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

Background
-
Function
IκB-α inhibits the activity of dimeric NF-kappa-B/REL complexes by trapping REL (RELA/p65 and NFKB1/p50) dimers in the cytoplasm by masking their nuclear localization signals. On cellular stimulation by immune and pro-inflammatory responses, becomes phosphorylated promoting ubiquitination and degradation, enabling the dimeric RELA to translocate to the nucleus and activate transcription[1][2][3][4][5][6].

Interacts with RELA; the interaction requires the nuclear import signal (PubMed:1493333). Part of a 70-90 kDa complex at least consisting of CHUK, IKBKB, NFKBIA, RELA, ELP1 and MAP3K14 (PubMed:9751059). Interacts with NKIRAS1 and NKIRAS2 (PubMed:10657303). Interacts with isoform 1 and isoform 2 of RWDD3; the interaction enhances sumoylation (PubMed:17956732, PubMed:23469069). Interacts with PRMT2 (PubMed:16648481). Interacts with PRKACA in platelets; this interaction is disrupted by thrombin and collagen (PubMed:20356841). Interacts with MEFV (PubMed:18577712). Interacts with DDRGK1; positively regulates NFKBIA phosphorylation and degradation (PubMed:23675531). Interacts with HNRNPA2B1; the interaction may be mediated by the RRM2 domain of HNRNPA2B1, and HNRNPA2B1 may interact simultaneously with FAM76B and either NFKBIA or NFKBIE to form a complex (PubMed:37643469)
