Analysis of Some Biochemical Properties of Recombinant Siberian Roe Deer (Capreolus pygargus) Chymosin Obtained in the Mammalian Cell Culture (CHO-K1).

Structure of the chymosin gene of Siberian roe deer (Capreolus pygargus) was established for the first time and its exon/intron organization was determined. Coding part of the chymosin gene of C. pygargus was reconstructed by the Golden Gate method and obtained as a DNA clone.

Single-domain antibody C7b for address delivery of nanoparticles to HER2-positive cancers.

Monoclonal antibodies (mAb) demonstrate great potential as immunotherapy agents for the treatment of diseases such as cancer as well as tagging for the targeted delivery of multicomponent therapeutic or diagnostic systems. Nevertheless, the large physical size, poor stability of mAbs and abnormal allergic reactions still remain the main issues affecting their generalised use. Single-domain antibodies (sdAb) are seen as the next generation of antibody derived therapeutics and diagnostics.

Species-specific identification of variola, monkeypox, cowpox, and vaccinia viruses by multiplex real-time PCR assay.

A method of one-stage rapid identification of variola (VARV), monkeypox (MPXV), cowpox (CPXV), and vaccinia (VACV) viruses, pathogenic for humans, utilizing multiplex real-time TaqMan PCR (MuRT-PCR) assay was developed. Four pairs of oligonucleotide primers and four hybridization probes with various fluorescent dyes and the corresponding fluorescence quenchers were concurrently used for MuRT-PCR assay. The hybridization probe specific for the VARV sequence contained FAM/BHQ1 as a dye/quencher pair; MPXV-specific, TAMRA/BHQ2; CPXV-specific, JOE/BHQ1; VACV-specific, Cy5/BHQ3.

Development of real-time PCR assay for specific detection of cowpox virus.

Background: The number of recorded human cowpox cases are recently increasing. The symptoms caused by cowpox virus (CPXV) in a number of human cases are close to the symptoms characteristic of the orthopoxviral human infections caused by monkeypox or smallpox (variola) viruses. Any rapid and reliable real-time PCR method for distinguishing cowpox from smallpox and monkeypox is yet absent.
