Low-Bandwidth and Non-Compute Intensive Remote Identification of Microbes from Raw Sequencing Reads
Cheap high-throughput DNA sequencing may soon become routine not only for
human genomes but also for practically anything requiring the identification of
living organisms from their DNA: tracking of infectious agents, control of food
products, bioreactors, or environmental samples.
We propose a novel general approach to the analysis of sequencing data in
which the reference genome does not have to be specified. Using a distributed
architecture we are able to query a remote server for hints about what the
reference might be, transferring a relatively small amount of data, and the
hints can be used for more computationally-demanding work.
Our system consists of a server with known reference DNA indexed, and a
client with raw sequencing reads. The client sends a sample of unidentified
reads, and in return receives a list of matching references known to the
server. Sequences for the references can be retrieved and used for exhaustive
computation on the reads, such as alignment.
To demonstrate this approach we have implemented a web server, indexing tens
of thousands of publicly available genomes and genomic regions from various
organisms and returning lists of matching hits from query sequencing reads. We
have also implemented two clients, one of them running in a web browser, in
order to demonstrate that gigabytes of raw sequencing reads of unknown origin
could be identified without the need to transfer a very large volume of data,
and on modestly powered computing devices.

O-phospho-L-serine, multi-functional excipient for B domain deleted recombinant factor VIII
Factor VIII (FVIII) is an important cofactor in the blood coagulation cascade. A deficiency or dysfunction of FVIII causes hemophilia A, a life-threatening bleeding disorder. FVIII circulates in plasma as a heterodimer comprising 6 domains (heavy chain, A1-A2-B and light chain A3-C1-C2). Replacement therapy using FVIII is the leading therapy in the management of hemophilia A. However, ∼15% to 30% of patients develop inhibitory antibodies that neutralize the activity of the protein. Neutralizing antibodies to epitopes in the lipid binding region of FVIII are commonly identified in patients' plasma. In this report, we investigated the effect of O-phospho-L-serine (OPLS), which binds to the lipid bindinding region, on the immunogenicity of B domain deleted recombinant factor VIII (BDDrFVIII). Sandwich enzyme-linked immunosorbent assay (ELISA) studies showed that OPLS specifically bind to the lipid binding region, localized in the C2 domain of the coagulation factor. Size exclusion chromatography and fluorescence anisotropy studies showed that OPLS interfered with the aggregation of BDDrFVIII. Immunogenicity of free-vs BDDrFVIII-OPLS complex was evaluated in a murine model of hemophilia A. Animals administered subcutaneous (sc) injections of BDDrFVIII-OPLS had lower neutralizing titers compared with animals treated with BDDRFVIII alone. Based on these studies, we hypothesize that specific molecular interactions between OPLS and BDDrFVIII may improve the stability and reduce the immunogenicity of BDDrFVIII formulations
