![Fig. 4. STA2-induced phosphorylation of MBS in intact platelets. The [32P] Pi-labeled platelets were stimulated with 1 μmol/L STA2 without stirring. MBS was immunoprecipitated with anti-MBS antibody, and phosphorylation of MBS was analyzed by SDS-PAGE and autoradiography (inset). Results were expressed as fold increase in the phosphorylation relative to the level at 0 seconds. Similar results were obtained in three other experiments with different donor platelets.](https://ash.silverchair-cdn.com/ash/content_public/journal/blood/90/10/10.1182_blood.v90.10.3936/3/bl_0019f4.jpeg?Expires=1724876267&Signature=UFd9NiEDPDhyn9pki5C9JFZtKmGU4CbYncs2b2J3I9rxxJGnnyyygSSdKu-NweZ7nuXwnocvG5DJTl0rPT83oDUfL90MTo1QYpWzGI9XrFynOezLSfSSroLMEmsJDGekfaEfM1RUlTv~zsZjid1X1wew4nzqUFxOg4p25olp9dBsIftKzeNgXCHU0sJuz-YT-pHCPBYnOjBhKOeos4~iXpfNI5JzA9qqt5R5A9WswrKWvTXWTt8XFK0j4hJ~gYQfj5AP4q5VxDb3UeyoQZuv5biR8bh16yHqZYk2YHUw5tBFid7xc5p-5jVepWKxMvsYrcxD7SjbiTl7PT607hNFlw__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
