状态
Lyophilized
溶解方式
Reconstitute the lyophilized product with deionized water (or equivalent) to make antibody concentration of 0.5 mg/mL.
缓冲液
PBS, pH 7.4, containing 0.02 % Sodium azide.
储存液
Sodium azide
注意事项
WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
注意事项
Avoid repeated freezing and thawing cycles.
储存条件
4 °C/-20 °C
储存方法
The antibody is stable in lyophilized form if stored at -20°C or below. The reconstituted antibody can be stored for 2-3 weeks at 2-8°C. For long term storage, aliquot and store at -20°C or below.

背景
Streptavidin is a tetrameric protein purified from Streptomyces avidinii. It has wide use in numerous molecular biological protocols dues to its strong affinity for biotin. NWSHPQFEK (Strep tag II) is a nine amino acid peptide with high specificity and affinity towards streptavidins.
