产品简介 

Tris(三羟甲基氨基甲烷)为弱碱，分子式为C4H11NO3，相对分子量为121.14, 在25℃下pKa为8.1，Tris缓冲液的有效缓冲范围在pH7.0～9.2之间。Tris碱的水溶液pH在10.5左右，一般加入盐酸调节pH值至所需值，即可获得该pH值的缓冲液。常用作生物缓冲液，常用pH值为6.8、7.4、8.0、8.8，其pH值随温度变化很大。一般来说，温度每升高1℃，pH值下降0.03。

Tris-HCl缓冲液(1mol/L,pH8.5,RNase free)属于pH缓冲液，采用进口Tris配制而成，再经15psi高压灭菌处理，常用于RNA相关实验。

注意事项 

1）对人体有刺激性，请注意适当防护。

2）为了您的安全和健康，请穿实验服并戴一次性手套操作。

Tris, or tris(hydroxymethyl)aminomethane, or known during medical use as tromethamine or THAM, is an organic compound with the formula (HOCH2)3CNH2. It is extensively used in biochemistry and molecular biology as a component of buffer solutions such as in TAE and TBE buffers, especially for solutions of nucleic acids.

"Tris" is a chemical compound used as a buffer. The full name is tris(hydroxymethyl)aminomethane. Tris has the ability to absorb counter ions (+H and -OH) so as to help keep the solution that they are in at a stable pH level. When the pH of Tris is set using HCl (hydrochloric acid) the buffer is called Tris HCl.
