Gram Stain Kit (MODIFIED BROWN AND BRENN) | BBS-2
產品介紹: 革蘭氏染色(Gram Staining)用來鑒別細菌的一種方法,利用細菌細胞壁上的生物化學性質不同,分成革蘭氏陽性(Gram Positive)與革蘭氏陰性(Gram Negative)。用於鑑別革蘭氏陰性和革蘭氏陽性。Gram Stain Kit (MODIFIED BROWN AND BRENN) 應用原理: 細菌的陽性和陰性細胞壁均由肽聚醣(peptidoglycan)組成(革蘭氏陽性細胞壁較厚),並且兩者都將吸收結晶紫(crystal violet)。革蘭氏陰性菌在肽聚醣壁的外部有一層脂多醣(lipopolysaccharide),在丙酮沖洗液中被破壞,從而使結晶紫(crystal violet)得以區分。這使革蘭氏陰性細菌吸收鹼性品紅染色(basic fuchsin stain)。
革蘭氏陽性細菌:藍色
革蘭氏陰性菌:紅色
其他組織:淡黃色-粉紅色
核:紅色
流程可概括為:染色-脫色-複染。(標準操作請依據原廠網站)
1.如有必要,對切片進行脫蠟(Deparaffinize sections)處理,然後水合成蒸餾水。
2.用龍膽紫溶液(Gentian Violet Solution)覆蓋組織切片,孵育2分鐘。
3.用蒸餾水沖洗玻片,以去除多餘的stain。
4.用Lugol’s Iodine Solution的碘溶液覆蓋組織切片,並孵育1分鐘。
5.在流動的自來水中沖洗滑片,以除去過量的碘(Iodine)。
6.浸入蒸餾水中1次。
7.滴加Gram的脫色劑(Gram’s Decolorizer dropwise),直到顏色不再滲出為止。
8.在蒸餾水中快速沖洗載玻片(2-5秒)。
9.用番紅O(Safranin O Solution)溶液覆蓋組織切片並孵育4分鐘。
10.在蒸餾水中快速沖洗載玻片以去除多餘的stain。
11.浸入無水酒精一次並吸乾。
12.用Picric Acid - Acetone Solution(0.1%)覆蓋組織切片,並在攪拌下孵育2-10秒。
13.用3種無水酒精(absolute alcohol)迅速脫水。
14.清除2種二甲苯或二甲苯替代物的更換,然後裝入合成樹脂(synthetic resin)中。
