摘要:
The present invention is related to the field of recombinant protein production using a synthetic gene associated with high protein expression in Pichia pastoris. More specifically, this invention describes the production of Sm14 Schistosoma mansoni recombinant protein. A synthetic gene was created to promote high Sm14 expression, and with this gene we obtained and genetically manipulated a Pichia pastoris strain for effectively producing a vaccine. We have also improved that protein's production and purification processes from P. pastoris cells; the industrial production of such processes may be scheduled.

The present invention refers to the subsampler and to a subsampling method that allows for the execution of environmental monitoring without the use of large sample volumes, thus ensuring specimen wealth and expedited analyses.
摘要:
The present invention refers to isolated DNA (deoxyribonucleic acid) molecules that encode for LigA and LigB proteins. The invention further refers to the use of fragments of these proteins in the diagnosis, and formulation of vaccines for prevention of infections caused by Leptospira in humans and animals.
摘要:
This invention refers to the construction of recombinant adenovirus with genes that codify for T.gondii SAG1, SAG2 and SAG3, through a homologue recombination technique between two vectors. A first vector that serves as transference vector of genes and a second vector that bears the adenoviral receptor genome of these genes. The invention is also related to the use of recombinant adenovirus in a vaccine composition to obtain the immunization against infections caused by T.gondii parasite.
摘要:
The invention relates to three isolated DNA molecules that encode for proteins, BigL1, BigL2 and BigL3, in the Leptospira sp bacterium which have repetitive Bacterial-Ig-like (Big) domains and their use in diagnostic, therapeutic and vaccine applications. According to the present invention, the isolated molecules encoding for BigL1, BigL2 and BigL3 proteins are used for the diagnosis and prevention of infection with Leptospira species that are capable of producing disease in humans and other mammals, including those of veterinary importance.
摘要:
The present invention refers to extracts from the fungus Guignardia sp., and also a new isolate compound from the aforementioned extract, both having antimicrobial activities, particularly antibacterial and antifungal activities, and their use in pharmaceutical compositions. The new compound, isolated from the extract of the fungus Guignardia sp., presents a dioxolanone ring, having the following formula:
摘要:
The present invention relates to peptide fragments which have one or more shared and/or similar amino acid sequences to amino acid sequences of specific portions of the 14 kDa protein of S. mansoni (Sm14) or related FABPs (Fatty Acid Binding Proteins), the said peptide fragments functioning as continuous or discontinuous epitopic regions of the molecule or mimicking its biological activity. More particularly, the present invention relates to a method for constructing active peptide fragments, peptide fragments, immunogenic composition and diagnostic kit using said peptide fragments.
摘要:
The purpose of the present invention is the production of recombinant virus through the cloning and expression of sequences of coding nucleotides of the whole or part of heterolog proteins, through the following method: (a) modification of the heterolog nucleotides sequences in such way they when cloned and expressed in the vector virus, they present in the 5′ region, nucleotides present in the 5′ edge of the gene NS1 of this vector virus or of other virus or equivalent functional sequences, and in its 3′ region, the correspondent genome region in the whole or part of the spheres of the steam and anchor of the protein E of this vector virus or equivalent functional sequences, and not compromising the structure and the replication of the mention vector virus; (b) insertion of the modified heterolog sequences in (a) in the intergene region at the structural protein E level and of on structural NS1 vector virus; (c) obtention of the non pathogenic recombinant virus and owner of the immunologic properties, having the heterolog sequences integrated in the viral genome according to the insertion described in (b) and, like that, expressing the heterolog antigene in such way that it can induce an appropriate immune response. The present invention is also addressed to vaccine compositions to immune against the Flavivirus and/or other pathogens.
