CD19 is a specific surface marker of B cells. A murine IgM-subtype antibody, 2E8, was generated previously and assigned to the CD19 category by the 6th International Workshop and Conference on Human Leukocyte Differentiation Antigens in 1996. In the present study, the 2E8 Fv gene was inserted into a baculovirus shuttle vector and novel protein was expressed in an IgG1 form in the Sf9 insect cel...

A vitamin K-dependent carboxylase has recently been purified from bovine liver microsomes and candidate cDNA clones have been isolated. Definitive identification of the carboxylase remains circumstantial since expression of candidate carboxylase cDNAs in mammalian cells is confounded by the presence of endogenous carboxylase activity. To overcome this problem, a recombinant strain of baculoviru...

Pemphigus vulgaris (PV) is an autoimmune blistering disease, in which autoantibodies against PV antigen (PVA or Dsg3) play a pathogenic role in inducing blister formation. Bacterial fusion proteins of PVA failed to absorb pathogenic autoantibodies from PV patients' sera probably because they did not represent the proper conformation. Therefore, a chimeric protein, PVIg, consisting of the whole ...

Soil temperature and humidity are important factors in affecting the condition of agricultural sector, which has an impact on quality quantity production. Lack information soil is one causes productivity deficiency process cultivation. The application technology field agriculture expected to be able reduce various adverse effects conditions. One by periodic monitoring, such as soil. This resear...

A putative novel rhabdovirus (SfRV) was previously identified in a Spodoptera frugiperda cell line (Sf9 cells [ATCC CRL-1711 lot 58078522]) by next generation sequencing and extensive bioinformatic analysis. We performed an extensive analysis of our Sf9 cell bank (ATCC CRL-1711 lot 5814 [Sf9L5814]) to determine whether this virus was already present in cells obtained from ATCC in 1987. Inverse ...

Normal dentin mineralization requires two highly acidic proteins, dentin sialoprotein (DSP) and phosphophoryn (PP). DSP and PP are synthesized as part of a single secreted precursor, DSP-PP, which is conserved in marsupial and placental mammals. Using a baculovirus expression system, we previously found that DSP-PP is accurately cleaved into DSP and PP after secretion into medium by an endogeno...

  Objective(s):  Infection by high-risk papillomavirus is regarded as the major risk factor in the development of cervical cancer. Recombinant DNA technology allows expression of the L1 major capsid protein of HPV in different expression systems, which has intrinsic capacity to self-assemble into viral-like particles (VLP). VLPS are non-infectious, highly immunogenic and can elicit neutralizing...
