【正文】 這條帶會很弱 ， 有時看不到 。 將冷卻至 65℃ 左右的瓊脂糖凝膠液，小心地倒在有機玻璃內(nèi)槽上，控制灌膠速度和量，使膠液緩慢地展開，直到在整個有機玻璃板表面形成均勻的膠層。每加完一個樣品，換一個加樣頭。 為了獲得電泳分離 DNA片段的最大分辨率，電場強度不應高于5V/cm（兩電極間的距離）。 DNA存在處顯示出紅色的熒光條帶。 Transport proteins and salt tolerance in plants Plant Science 164 (2022) 891_/900 . Mansour, , . Salama, . AlMutawa Evidence indicates that plant salt tolerance operates at a cellular level. Commonly proposed cellular mechanisms include ion sequestration in vacuoles or ion exclusion at plasma membranes. Plasma membrane ATPase and vacuolar ATPase and pyrophosphatase are proton pumps that provide an energy source for transport of ions across the plasma membrane and tonoplast, respectively. Membrane Na+/H+ antiporters take advantage of the pro
