Goat Anti-Human IgG (AF405) - Secondary antibody, IgG

Cat. No.: Ab181959
AVAILABLE TO ORDER
GRADE & PURITY Validated ? Validated grade — performance confirmed in defined applications before release. Use when you want documented assurance the reagent works as stated. ExactAb™ ? ExactAb™ — Aladdin's antibody line emphasizing precision and validated quality. Use for reliable, specificity-validated antibody applications. Ex:401nm ? Fluorescence excitation maximum at 401 nm — the wavelength of light that best excites this fluorophore. Match it to your instrument's laser or filter set for the strongest signal. Em:422nm ? Fluorescence emission maximum at 422 nm — the wavelength this fluorophore emits after excitation. Use it to pick the right detection filter and avoid channel cross-talk. 1.0 mg/mL

Goat Anti-Human IgG (AF405) (Ab181959) - IF
IF analysis of EGFR (blue) in A431 cells. The cells were fixed and permeabilized with 100% methanol for 5 minutes, and blocked with 2% BSA for 1 hour at room temperature. Cells were stained with Serclutamab (anti-EGFR) (Ab182867) at 1/1500 dilution in blocking buffer overnight at 4°C, and then incubated with Goat Anti-Human IgG (AF405) (Ab181959) at a dilution of 1/500 for 1 hour at room temperature in the dark (blue). PBS instead of the primary antibody was used as the secondary antibody only control. Cells were counterstained with PI (red). Images were taken on the confocal laser scanning microscope.

Goat Anti-Human IgG (AF405) (Ab181959) - Flow Cytometry
Flow Cytometry analysis of A431 cells labelling CD276 (red) with Mirzotamab (anti-CD276) (Ab182952). Goat Anti-Human IgG (AF405) (Ab181959) at a dilution of 1/1000 was used as the secondary antibody. Blue - Isotype control, Human IgG (Ab170213). Black - Unlabelled control, cells without incubation with primary antibody.
