We present an unprecedentedly comprehensive characterization of protein
dynamics across early development in Xenopus laevis, available immediately via a convenient
Web portal. This resource allows interrogation of the protein expression data in conjunction with
other data modalities such as genome wide mRNA expression. This study provides detailed
data for absolute levels of ~14K unique Xenopus proteins representing homologues of ~9K
unique human genes -- a rich resource for developmental biologists. The purpose of this
manuscript is limited to presenting and releasing the data browser.
