PBST(phosphate buffered solution)即含吐溫-20的磷酸鹽緩沖液,能夠提供相對穩(wěn)定的離子環(huán)境和pH緩沖能力,是生物學(xué)中經(jīng)常使用的緩沖鹽溶液,主要用于免疫組化和原位雜交,酶聯(lián)免疫等實(shí)驗(yàn)中,清洗免疫印跡膜等。產(chǎn)品為無色液體,pH為7.2-7.4(25℃),主要成分為磷酸二氫鉀、磷酸氫二鈉、氯化鈉以、氯化鉀以及吐溫-20。
本產(chǎn)品為10×原液,不可直接使用,需要稀釋到1×工作液使用。 4℃保存可延長產(chǎn)品保質(zhì)期,長期不用建議低溫保存。
注意事項(xiàng)
低溫儲(chǔ)存較易產(chǎn)生沉淀。如果發(fā)現(xiàn)有沉淀產(chǎn)生,請搖晃或置于37℃水浴至完全溶解后再使用。
為了您的安全和健康,請穿實(shí)驗(yàn)服并戴一次性手套操作。
A 10X Concentrated solution of Phosphate Buffered Saline with Tween® 20. The 10X Concentration is 80mM Na2HPO4, 1.5M NaCl, 20mM KH2PO4, 30mM KCl, 0.5% Tween® 20, pH 7.4.
PBST is commonly used as a wash solution for Western blot membranes and microtiter plate wells in ELISA assays. The Phosphate Buffered Saline with Tween® 20 is an optimal formulation of pH stabilizers, salts and detergents designed to effectively remove excess material from membranes and microtiter plate wells without disrupting the antigen/antibody binding reaction.
By maintaining the proper buffering environment, unbound components can be washed away without suppressing antigen-antibody binding interactions, thereby reducing nonspecific background and increasing the specific signal.
