228 results about "Order Scorpiones" patented technology

Scorpions are predatory arachnids of the order Scorpiones. They have eight legs and are easily recognized by the pair of grasping pedipalps and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. Scorpions range in size from 9 mm / 0.3 in.

Sea cucumber health-care wine and brewing method thereof

The invention discloses a sea cucumber health-care wine and a brewing method thereof. On the basis of the white spirit as the base solution, the sea cucumber health-care wine contains the following raw materials in percentage by weight: 10-60% of sea cucumber enzymolysis solution, 1-20% of Chinese medicinal herb leaching solution, 0.1-0.5% of honey and the balance of water. The Chinese medicinal herb leaching solution is composed of 2-5 parts of acanthopanax bark, 3-8 parts of wolfberry fruit, 1-5 parts of angelica, 2-5 parts of scorpion, 2-7 parts of kudzu root, 1-3 parts of black ant and 4-8 parts of licorice. The brewing method comprises the following steps: cleaning sea cucumbers, boiling, carrying out enzymolysis, blending with the Chinese medicinal herb leaching solution subjected to soaking in white spirit and honey, and seasoning to obtain the sea cucumber health-care wine. The invention has the advantages of abundant nutrition, low nutrition loss of sea cucumbers in the preparation process, sufficient soaking of Chinese medicinal herbs, and favorable health-care function, has the effects of strengthening the constitution, tonifying the blood, moistening dryness, preventing cancers and relieving tiredness, and can be easily absorbed by the human body; and the invention is low in cost, and thus, is beneficial to popularization.

Method for producing recombinant scorpion toxin protein by adopting silkworm as parasitifer

The invention discloses a method for producing recombinant scorpion toxin protein by adopting a silkworm as a parasitifer, which mainly comprises the following steps: adopting a scorpion cDNA as a template, adopting 5'-ACGTAGATCTATGGATGGATATATAAG-3' containing BglII enzyme cutting site as a forward primer and adopting 5'-ACGTAGATCT TTACTTTTTTCCAC-3' containing the BglII enzyme cutting site as a reverse primer to carry out PCR gene amplification reaction in 32 cycles to obtain a scorpion toxin gene; digesting pCR2.1-scorpion toxin by restriction endonuclease BglII to obtain a scorpion toxin gene fragment; cloning the scorpion toxin gene fragment in a baculovirus transfer vector pAcGP67b to obtain a recombinant pAcGP67b-scorpion toxin gene, carrying out homologous recombination with baculovirus BmNPV DNA of a silkworm in an insect cell by cotransfection to produce a recombinant virus; expressing in a silkworm body and purifying the recombinant scorpion toxin. Most of the recombinant scorpion toxin protein expressed by a silkworm larva is retained in a fat body of the silkworm; the scorpion toxin is purified from the fat body by an affinity chromatography; and the recombinant scorpion toxin has obvious biological toxicity, is suitable for the requirement of a biopharmaceutical industrialization level and has wide application prospect in the field of future medical and clinic treatment.

The invention discloses methods for culturing and preserving syntrichia caninervis mitt. protonemata. The method for culturing syntrichia caninervis mitt. protonemata comprises the following steps: firstly selecting proper materials, carrying out washing, sterilizing, washing, air-drying, grinding and other treatments on the proper materials, then inoculating moss pieces to a BG11 solid culture medium, carrying out induction culture on the moss pieces in an illuminating incubator under the conditions that the temperature is 22 DEG C, the illumination intensity is 27mu mol.m<-2>.s<-1> and the light/dark time is 14h/10h until the protonemata appear and then transferring the protonemata to liquid culture for progressive expanding propagation. The method for preserving syntrichia caninervis mitt. protonemata is characterized in that after being collected, the protonemata are naturally air-dried, are filled in sealed plastic bags and then are preserved at - 80 DEG C. The methods are beneficial to mass artificial expanding propagation of syntrichia caninervis mitt.; the protonemata can be developed into new plants, which provides a new way for artificial expanding propagation of syntrichia caninervis mitt.; and the methods have broad application fields.

Human antibody variants that specifically recognize the toxin CN2 from Centruroides noxius scorpion venom

InactiveUS20070071750A1Sugar derivativesBacteriaCentruroides noxiusAntibody fragments
The present invention is directed to recombinant human antibodies specific for Cn2 toxin from C. noxius scorpion venom. The antibodies are able to recognize the toxin and preferably neutralize it as well as the whole venom of C. noxius scorpion. This invention is also directed to a human non-immune phage display library. One clone that specifically binds the Cn2 toxin was affinity matured by directed evolution. Three cycles of maturation were performed and several scFv clones were isolated which specifically recognize toxin Cn2 with increased Kd of 446 fold. All variants were monomeric and only variants 6009F, 6105F and 6103E showed to be capable of neutralizing toxin Cn2 and the whole venom. Variant 6009F recognizes a different epitope than that of BCF2, a murine monoclonal antibody raised against scorpion toxin Cn2 which is also capable of neutralizing both Cn2 toxin and the whole venom when tested in mice, as well as that of commercially available polyclonal antibody fragments antivenom from horse. The scFv 6009F is the first reported recombinant human antibody fragment capable of neutralizing a scorpion venom. These results pave the way for the generation of safer autologous recombinant neutralizing antivenom against scorpion stings. The antibodies of the present invention can be used as part of a composition to treat those in need of treatment including those already stung by one or more scorpions, particularly C. noxius scorpions.
