MB082-PC: Spin Column for Plasmid Miniprep
* Spin columns are compatible to reagents in plasmid miniprep kits from most of other manufacturers, such as Qiagen and Sigma. The yield is similar. Thus, clients do not have to waste reagents from plasmid miniprep kits.
* Low cost spin columns: $85 for 200 universal spin columns. A promotion is running: 20% discount of spin columns for plasmid miniprep as credit to purchase any other products or services on sydlabs.com from August 1 to October 31, 2022. Limited to new customers.
* Syd Labs provides the recipe of reagents for plasmid miniprep if you buy spin columns from us. Very simple to make the reagents. The shipping fee is much lower if you buy spin columns only rather than the whole DNA purification kits with heavy and bulky reagents.
