半岛bd体育手机客户端 说明
一般描述
Fragment mixture prepared by cleavage of pBR322 DNA with restriction endonuclease Hae III.
Size Range:8 to 587 bp
应用
DNA Molecular Weight Marker V is used for the size determination of DNA in agarose gels. It simplifies accurate molecular weight determination of double-stranded DNA fragments generated by:
组分
Ready-to-use solution, 250μg/ml, in TE buffer (10mM Tris-HCl, 1mM EDTA, pH 8.0)
序列
The mixture contains 22 DNA fragments with the following base pair lengths (1 base pair = 660 daltons): 8, 11, 18, 21, 51, 57, 64, 80, 89, 104, 123, 124, 184, 192, 213, 234, 267, 434, 458, 504, 540, and 587 as determined by computer analysis of the pBR322 sequence.
Note: Fragment lengths are derived from computer analysis of the DNA sequence. Depending on the size range of the marker, the smallest fragments will only be visible on overloaded gels.
单位定义
50 μg = 1A260unit
制备说明
Activator:Ammonia, pyridine, imidazole, all at pH >7; detergents
