CD103 Rat mAb - Primary antibody, specific to CD103, Rat IgG2a

Cat. No.: Ab093648
AVAILABLE TO ORDER
GRADE & PURITY Carrier Free ? Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays. Validated ? Validated grade — performance confirmed in defined applications before release. Use when you want documented assurance the reagent works as stated. Azide Free ? Azide-free — without sodium azide preservative. Use in conjugations, cell work, or assays where azide is toxic or inhibitory. PBS Only ? PBS-only formulation — supplied in phosphate-buffered saline with no other additives. Use when you need a clean PBS buffer free of stabilizers/carriers. ≥95%(SDS-PAGE) See COA

CD103 Rat mAb (Ab093648) - Flow Cytometry
Two-color flow cytometric analysis of CD103 expression on mouse lymph node cells. C57BL/6 mouse lymph node cells were stained with CD3 Rat mAb (APC) (Ab185408) and either Rat IgG Isotype Control Antibody (Biotin) (Ab180310; Left panel) or CD103 Rat mAb (Ab093648; Right panel) at 0.5 μg/mL. Two-color flow cytometric dot plots showing the correlated expression of CD3 versus CD103 (or Isotype control staining) were derived from gated events with the forward and side light-scatter characteristics of viable mononuclear cells.
