Most notably, go ahead and throw the Major third (3 draw, 7 draw, or the 10' blow bend) and the sixth (2 blow, 5 blow, and 8 blow) into your playing!
Here are some great notes from Wikipedia on the Mixolydian mode. Basically, it is the scale that almost all blues chords are based off of. Take any generic 12 bar blues with a I IV V pattern...the notes of this scale all "fit" (that's an oversimplification of the IV and V chord tones, but good enough for now).
Note that the flat third and flat fifth ARE NOT a part of the Dominant chords that make up the blues scale. While they sound good and create bluesy phrases, this illustrates that the Major third and sixth of the scale are just as appropriate to play. This will give you less of a blues vibe and sound more rock-ish.
