Isotype control antibodies are used to estimate the nonspecific binding of target primary antibodies due to Fc receptor binding or other protein-protein interactions. An isotype control antibody should have the same immunoglobulin type and be used at the same concentration as the test antibody.

PCNA was immunoprecipitated from 0.2 mg HeLa cell lysate with HA601172 at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using HA601172 at 1/10,000 dilution. Anti-Mouse IgG for IP Nano-secondary antibody (NBI02H) at 1/5,000 dilution was used for 1 hour at room temperature.

PCNA was immunoprecipitated from 0.2 mg PC-12 cell lysate with HA601172 at 2 µg/10 µl beads. Western blot was performed from the immunoprecipitate using HA601172 at 1/10,000 dilution. Anti-Mouse IgG for IP Nano-secondary antibody (NBI02H) at 1/5,000 dilution was used for 1 hour at room temperature.

Flow cytometric analysis of HeLa cells labeling eIF-6.
Cells were fixed and permeabilized. Then stained with the primary antibody (HA601293, 1μg/mL) (green) compared with Recombinant Mouse IgG1 (HA601336, 1μg/mL) (red). After incubation of the primary antibody at +4℃ for an hour, the cells were stained with a iFluor™ 488 conjugate-Goat anti-Mouse IgG Secondary antibody (HA1125) at 1/1,000 dilution for 30 minutes at +4℃. Unlabelled sample was used as a control (cells without incubation with primary antibody; black).
Flow cytometric analysis of C6 cells labeling eIF-6.

☑ Cell treatment (CT)
Chromatin immunoprecipitations were performed with cross-linked chromatin from HeLa cells treated with 500ng/mL TSA for 4 hours with Histone H3 (acetyl K27) (HA600047) or Recombinant Mouse IgG1 (HA601336) according to the ChIP protocol. The enriched DNA was quantified by real-time PCR using indicated primers. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
