• 介紹：

  活力定義：在40℃和pH7.5條件下，非特異性蛋白酶活性的單位增加了酪蛋白中福林-陽性氨基酸和肽的釋放速度。一單位(U)可釋放1μmol/min酪氨酸。

  最適PH：7.0-8.0。

  最適溫度：35-40 °C。

  分子量：20000～60000。

  性狀：白色或微褐色粉末。

  來源：灰色鏈霉菌。

  穩(wěn)定劑：鈣離子保護效應(yīng)：
  該制劑中含20%的醋酸鈣，用于其穩(wěn)定性。按照現(xiàn)行的質(zhì)量控制程序，它不含淀粉。含有0.01-0.1M鈣的稀釋溶液，在4到8℃的中性pH下，其活性在24小時內(nèi)是穩(wěn)定的。鏈霉素蛋白酶也可以通過低水平的鈣來防止熱失活。
