Figure 3From: Sandwich ELISA for quantitative detection of human collagen prolyl 4-hydroxylaseComparison of the detection antibodies produced by different manufacturers. Purified C-P4H was measured with the sandwich ELISA using different pab-β antibodies: pab-β A (Abcam), pab-β B (Calbiochem, Germany), pab-β C (Santa Cruz Biotechnology, Inc.) and pab-β D (Stressgen Bioreagents). The error bars show the ± SD of three parallel experiments.Back to article page
