![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=1735545187&Signature=0trOLw~HADn2XRhwrcS7rDAXQkAX4B5aUzJ~x3tz2gXsbo5o4AE0OY8ioscLIIcQeZpRm4x~WglbCiSHe8XNlka9M-lxiDZadDj1nR5P5mmEQbFpvTzFD5zybd06A5pE2vrwhLClac7nl88lpeCdrdo28PJzEclMoEpa5rokUth3psyiW7SvCotyFjh8jF2Qfu2LC5clNXYuzzBhPs2OrH9qFt-BwlENVZhuTAOBIBECTxa~8qZnuKSLQkrixE7xrelLo~~KYywzjf-rdROF~ct5CNHk-rgeGTcP1UDqEQtkc7x5aJje2Vz7UBewYg-9AF2W6fD3VRrSGIByKRZUNQ__&Key-Pair-Id=APKAIE5G5CRDK6RD3PGA)
