Human red blood cells (RBC) undergo a sudden change from blocking to passing through 1.3 +/- 0.2-micrometer micropipettes at a transition temperature (Tc) of 36.4 degrees C. For resealed RBC ghosts this transition occurs at 28.3 degrees C (Tg). These findings are attributed to an elastomeric transition of hemoglobin from being gel-like to a fluid and to an elastomeric transition of membrane proteins such as spectrin. Spectrin shows a uniform distribution along the aspirated RBC tongue above Tg in contrast to the linear gradient below Tg.
人类红细胞（RBC）在36.4摄氏度的转变温度（Tc）下，会突然从阻塞状态转变为能够通过1.3±0.2微米的微量移液器。对于重新密封的红细胞空壳，这种转变发生在28.3摄氏度（Tg）。这些发现归因于血红蛋白从凝胶状到流体状的弹性转变，以及诸如血影蛋白等膜蛋白的弹性转变。与Tg以下的线性梯度相反，血影蛋白在Tg以上沿吸出的红细胞舌呈现均匀分布。
