  3. what is the approximate molecular weight of this DNA.(Cat. no. 2618-250)

    1 answer

    1. This product is a highly polymerized, high molecular weight, uncut preparation - likely tens of thousands of base pairs in length. Average size is not determined for this product.

      If you would like a product with a tested molecular weight, we offer product D4764 which is the genomic DNA from calf thymus as well. It is unsheared and has the molecular weight >20 kb. Please enclosed the product web page: https://www.sigmaaldrich.com/catalog/product/sigma/d4764?lang=en&region=GB&cm_sp=Insite-_-prodRecCold_xviews-_-prodRecCold10-2

      We also offer Product D4416 which is DNA that is categorized as high molecular weight DNA with the molecular weight >50 Kilo-base pair (kbp- same as kb): https://www.sigmaaldrich.com/catalog/product/sigma/d4416?lang=en&region=GB However this product is isolated from adult BALB/c mice.
