Answer

Thank you for your patience. My colleague has informed me that we ship via FedEx to Columbia, and the transit time is usually 2 days. These proteins will be shipped on ice packs, and we would not expect the shipping to effect the quality. We will guarantee all of our products to work as stated on their datasheets for six months from the date of purchase. If for any reason you are not satisfied with these proteins, please let us know and we will be happy to refund or replace them for you.

Answer

Thank you for contacting us. We generally ship these proteins overnight on an ice pack at 4C. The lyophilized protein ab119745 should be stable for longer shipment at ambient temperature, but the liquid protein may not be. I am currently checking with my colleague who coordinates our South American orders to check what shipping methods are used for Columbia. I will let you know as soon as I have any additional information.
