Goat Anti-Rabbit IgG H&L (AF488) - Secondary antibody, IgG

Cat. No.: Ab138205
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. High Performance ? High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short. Ex:490nm ? Fluorescence excitation maximum at 490 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:525nm ? Fluorescence emission maximum at 525 nm — the wavelength this fluorophore emits after excitation. Use it to pick the right detection filter and avoid channel cross-talk. 1 mg/mL

Goat Anti-Rabbit IgG H&L (AF488) (Ab138205) - ICC/IF
IF analysis of HeLa cells labeling PABPN1 with purified PABPN1 Rabbit mAb (Ab119979) at 1/200 dilution. 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 counterstained with beta Actin Mouse mAb (Ab155822) at 1/500 dilution - Goat Anti-Mouse IgG H&L (AF647) 1/1000. Goat Anti-Rabbit IgG H&L (AF488) (Ab138205) was used as the secondary antibody at 1/500 dilution. DAPI was used as nuclear counterstain. PBS instead of the primary antibody was used as the secondary antibody only control. Images were taken on the confocal laser scanning microscope.
