NTC is an industry leading provider of highly-purified plasmids. Ordering plasmids from NTC a fast and easy 2 step process and there is no where else you will receive the attention to detail and great service for the cost.

Timeline: First time orders require 2-3 weeks. Reorders can be from 1 day to two weeks, depending upon the arrangements made (just in time re-ordering is by prior agreement).

1) Call NTC for a quotation. Best pricing is available based on quantity ordered and copy number. Most high-copy plasmids have a pUC origin of replication, or equivalent, and result in the lowest cost. NTC is a longtime industry leader in quality and cost-effectiveness.

2) Send NTC 1mcg of your plasmid DNA, spotted on Whatman 3MM or FTE filter paper, together with NTC’s Small Scale online order form filled out. (The form is designed to prompt you for all information needed for propagation and diagnostic testing.)

NTC will:

  • Transform the production host.
  • Prepare a glycerol stock using “low metabolic burden technology” , (http://www.genengnews.com/articles/chtitem.aspx?tid=2819).
  • Grow, and purify the desired quantity of pDNA, using endotoxin-free reagents and procedures.
  • At no additional cost, NTC will also formulate the DNA according to specification (default is 0.5mg/ml in TE buffer).
  • A small-scale certificate of analysis will be provided, including: gel photo (digested and undigested DNA, ladder), concentration and quantity
