That’s because the Pacific hagfish has already been genetically sequenced. Josh Kogot, a biochemist at Naval Surface Warfare Center, Panama City Division, said in a telephone interview that using the Pacific hagfish allowed researchers to work quickly by specifically looking into its DNA sequence and proteins. The slime they’re interested in is a combination of two proteins and saltwater. Kogot said it took about six months to reproduce the slime into a filament. “What’s fascinating to me is just how simple in the grand scheme of things this system is. It’s really a two-protein system with seawater, and it’s able to be this strong and expansive,” he said. “It can expand 10,000 times in volume in milliseconds.” To create the proteins, Kogot grew them in separate petri dishes filled with E. coli bacteria, isolated and purified them, and then combined them using a centrifuge. Researchers knew they had successfully duplicated the slime by examining their version with a scanning electron microscope. Kogot said no special equipment was necessary, either. It’s all equipment most biotechnology researchers already have. The filament that’s created is stored in a screwtop vial and kept in a refrigerator when it’s not in use, although it maintains its properties at room temperature. Kogot said some practical-application testing on the material has already begun, but he did not elaborate for what uses. Right now, his team is looking for ways to increase the duplicated slime’s ability to attach to different surfaces, potential delivery systems, and enhancing its stability in different environments, according to the Navy. Kogot said it’s too early to tell when a product using the synthetic slime could be integrated into the fleet, but testing on specific applications could begin within six months to a year.<\/p>\n","protected":false},"excerpt":{"rendered":" It looks and feels a lot like snot, but Navy researchers believe slime produced by the primitive hagfish could help save lives.<\/p>\n","protected":false},"author":7,"featured_media":40626,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_yoast_wpseo_meta-robots-noindex":"","_yoast_wpseo_meta-robots-nofollow":"","_yoast_wpseo_canonical":"","_acf":"","_yoast_wpseo_primary_category":70,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","_smg_distribution_targets":[]},"categories":[12,70],"tags":[],"coauthors":[1715],"class_list":["post-19014","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news","category-your-army"],"acf":{"subheadline":"","legacy_arc_id":"TSUDAZUIDNF3VL7TW7EJYMGKRA","arc_canonical_url":"\/news\/your-navy\/2017\/02\/12\/expanding-slime-has-captured-the-imagination-of-navy\/","remove_feature_photo":false,"is_sponsored":false,"subtype":"","redirect_url":"","disable_inline_ads":false,"native_logo_pretext":"Presented By:"},"yoast_head":"\n
