Complement C4d antibody

Catalog No. ABIN6173841

Product Details anti-Complement C4d Antibody

Target: Complement C4d (C4d) (Complement Component C4d (C4d))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This Complement C4d antibody is un-conjugated

Application: Immunofluorescence (IF), ELISA, Coating (Coat), Immunohistochemistry (Formalin-fixed Sections) (IHC (f))

Purpose: Mouse Monoclonal anti-Complement C4d (C4D204), Purified, BSA-free

Characteristics: This MAb is specific to Complement 4d (C4d) and it reacts with the secreted as well as cell-bound C4d.C4d is a degradation product of the activated complement factor C4b. Complement 4b is typically activated by binding of Abs to specific target molecules. Following activation and degradation of the C4 Molecule, thio-ester groups are exposed, which allow transient, covalent binding of the degradation product Complement 4d to endothelial cell surfaces and extracellular matrix components of vascular basement membranes near the sites of C4 activation. The presence of C4d in peritubular capillaries is a key indicator for acute humoral (i.e. antibody-mediated) rejection of kidney, heart, pancreas and lung allografts. As an established marker of antibody-mediated acute renal allograft rejection and its proclivity for endothelium, this component can be detected in peritubular capillaries in chronic renal allograft rejection as well as hyperacute rejection, acute vascular rejection, acute cellular rejection, and borderline rejection. It has been shown to be a significant predictor of transplant kidney graft survival. Anti-C4d, combined with anti-C3d, can be utilized as a tool for diagnosis of allograft rejection that may warrant a prompt and aggressive anti-rejection treatment. Primary antibodies are available purified, or with a selection of fluorescent CF® dyes and other labels. CF® dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF®405S and CF®405M are not recommended for detecting low abundance targets, because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.

Application Details

Application Notes: Immunohistology formalin-fixed 1:200-1:400

• Staining of formalin-fixed tissues requires boiling tissue sections in 10 mM Tris with 1 mM EDTA,  pH 9.0, for 10-20 min followed by cooling at RT for 20 minutes
• Immunofluorescence 1:50-1:100
• ELISA For coating use Ab at 1-2 μg/mL, order Ab without BSA
• Optimal dilution for a specific application should be determined by user
