Experimental details: Western blot analysis of CD55/DAF using 30 µg of A431 lysate. Samples were loaded onto a 10% SDS-PAGE gel and probed with a CD55/DAF polyclonal antibody (Product # PA5-29657) at a dilution of 1:1000.

Experimental details: Knockdown of Complement decay-accelerating factor was achieved by transfecting HeLa cells with Complement decay-accelerating factor specific siRNAs (Silencer® select Product # S534833, S3906). Western Blot analysis (Fig. a) was performed using Whole cell extracts from the Complement decay-accelerating factor knockdown cells (lane 3), non-targeting scrambled siRNA transfected cells (lane 2) and untransfected cells (lane 1). The Blot was probed with CD55 Polyclonal Antibody (Product # PA5-29657, 1:1000 dilution) and Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4000 dilution). Densitometric analysis of this western Blot is shown in histogram (Fig. b). Decrease in signal upon siRNA mediated knock down confirms that antibody is specific to Complement decay-accelerating factor.

Experimental details: Western Blot was performed using Anti-CD55 Polyclonal Antibody (Product # PA5-29657) and a 70 kDa band corresponding to Complement decay-accelerating factor was observed across positive cell line (HeLa); and not across negative cell lines (IMR-32 and SH-SY5Y). Whole cell extracts (30 µg lysate) of HeLa (Lane 1), IMR-32 (Lane 2) and SH-SY5Y (Lane 3) were electrophoresed using NuPAGE™ 10% Bis-Tris Protein Gel (Product # NP0301BOX). Resolved proteins were then transferred onto a Nitrocellulose membrane (Product # IB23001) by iBlot® 2 Dry Blotting System (Product # IB21001). The Blot was probed with the primary antibody (1:1000 dilution) and detected by chemiluminescence with Goat anti-Rabbit IgG (H+L) Superclonal™ Recombinant Secondary Antibody, HRP (Product # A27036, 1:4000 dilution) using the iBright FL 1000 (Product # A32752). Chemiluminescent detection was performed using Novex® ECL Chemiluminescent Substrate Reagent Kit (Product # WP20005).
