Expression profiling of zebrafish β1 paralogs during development. Expression of the different paralogs at 2, 4, 6, 8, 12, 14, 24, 48, 56, 72 and 96 hpf (hours post fertilization) was analyzed by semiquantitative RT-PCR using primers designed against a portion of extracellular domains of the different paralogs. The amplification of zebrafish β-actin was monitored as a positive control.
