Biological Buffers
生物緩衝液具有惰性，且對受測系統僅有短期影響，這兩點都是相較於過去使用的無機物質和弱有機酸的明顯優勢。當今使用的大多數生物緩衝液為 N-取代牛磺酸或甘氨酸緩衝液，能滿足生物緩衝液所需達到的大部分要求。緩衝系統通常應用於實驗中，以便能直接比較結果。

Buffers, TE solutions 10X concentrates (TRIS-EDTA buffer)
Supplier: ROCKLAND
TE buffer is a commonly used buffer solution in molecular biology, especially in procedures involving DNA, cDNA or RNA. "TE" is derived from its components: Tris, a common pH buffer, and EDTA, a molecule that chelates cations like Mg2+. The purpose of TE buffer is to solubilize DNA or RNA, while protecting it from degradation.
