There was no past or family history of tuberculosis ... The image shows the presence of numerous acid-fast bacilli (arrows; Ziehl-Neelsen stain, 20% sulfuric acid, magnification ×1,000).

They both grew on Löwenstein–Jensen medium, Sabouraud agar medium and blood agar medium. Both bacteria appeared acid-fast by Ziehl–Neelsen stain and Gram-positive by Gram stain. The identification was ...

SYBR14是一种绿色荧光核酸染料，属于膜渗透性DNA结合探针，主要用于活细胞核酸的特异性标记。 其化学结构属于花青素类衍生物，以5mM DMSO溶液形式储存，需在-20℃避光干燥保存（有效期≥1年），运输需低温保护（冰袋运输）。 与DNA结合后荧光强度增强20倍以上 ...

主要结合双链DNA（dsDNA），对双链RNA（dsRNA）有较弱结合，对单链核酸结合力极弱。 细胞活力区分： 活细胞：因细胞膜完整，SYBR 14可渗透进入，将细胞核染成明亮绿色。 死细胞：膜完整性丧失，SYBR 14无法进入，需依赖碘化丙啶（PI）染色（红色荧光）。 嵌插 ...
