1/25000 - 1/100000. Detects a band of approximately 130 kDa (predicted molecular weight: 49 kDa). 1/25000 - 1/100000. Detects a band of approximately 130 kDa (predicted molecular weight: 49 kDa). This product has been tested by Western blotting using a LexA-Rb fusion and a LexA-PP2A, beta subunit fusion expressed in budding yeast. The observed molecular weight of a fusion protein will be increased by approximately 24 kDa due to the addition of the LexA DNA binding domain.

The LexA protein of Escherichia coli is a transcriptional repressor regulating approximately 20 genes, many of which are involved in DNA repair (SOS response). It binds with variable affinity to single, double, or even triple-operators via its amino-terminal domain that contains three alpha-helices spanning residues. This characteristic of LexA protein has been used to make efficient baits for two-hybrid studies. -
