CoatingofPlateletswithAntibodyinvitro
OUTLINEAntibody-coated platelets (opsnized) may be used in the subsequent thrombophagocytosis assay. PROTOCOLResuspend 1.6x10^8 of CMFDA-labeled platelets in 200µl of BSGC-BSA (v/w 1%) either with a control Ab or an Ab directed to platelet Ag (you may use Grener F-bottom microtitration plate for this step). If the Ab used is rat IgG1 (k) against mouse CD41 (MWReg30, Becton Dickinson, Cat.: 09911D) then the advis......阅读全文

关于冰冻血小板的质量
"冰冻前及融化后使用前22±2℃平衡4h"肯定是没有必要的。"37℃静止水浴融化"要改为38℃循环水浴融化。将冷却速度控制在－1℃/min（不是2±1℃/min）左右尤其是-15℃～-40℃之间是关键；运输不能用冰盒，否则冰冻保存失败（常见）；冷冻时冰箱温度低于-60℃（放入时开盖时间过长或冰箱制冷
