CD200/OX2 Rat mAb (FITC) - Primary antibody, specific to CD200/OX2

Cat. No.: Ab190189
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:498nm ? Fluorescence excitation maximum at 498 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:517nm ? Fluorescence emission maximum at 517 nm — the wavelength this fluorophore emits after excitation. Use it to pick the right detection filter and avoid channel cross-talk. 0.5 mg/mL
