Extensive characterization of NF-κB binding uncovers non-canonical motifs and advances the interpretation of genetic functional traits

Table 1 Comparison and validation of p52p52

	SELEX1	SELEX3
Number/proportion of 10-mer sequences (n = 522,857) that were enriched	14,758 (2.8%)	11,065 (2.1%)
Number of 10-mer sequences shared with microarrays (n = 757)	249^a (32.9%)	196^b (25.9%)
Number of 10-mer sequences shared with Linnell et al. [13] (n = 63)	21^c (33.3%)	18^d (28.6%)

Hypergeometric probability test for over-representation: ^aP = 6.9e-187; ^bP = 3.1e-148; ^cP = 2.3e-19; ^dP = 1.5e-17. Number of enriched sequences identified during SELEX and overlaps with two microarray datasets (ours and Linnell et al. [13]).
