A simple, fast and quantitative single-step dead-cell indicator for flow cytometry
Jixiang Liu, Jolene Bradford, Chris Langsdorf, life technologies,
We have evaluated a series of new compounds for dead cell stain and identified a new product, SYTOX® AADvancedTM dead cell stain, which demonstrates improved properties over 7-AAD. These properties make the SYTOX® AADvancedTM dead cell stain a simple, fast and quantitative single-step no-wash dead-cell indicator as well as ideal for use in multicolor application requiring DNA content.

The evidence for an association between autoimmune diseases and chronic HCV infection has been clearly established. To this aim, a protein array was employed to analyze serum samples of HCV patients w/wo autoimmune complications, of patients with autoimmune hepatitis but not infected with HCV and of healthy donors as controls. A panel of autoantigens able to discriminate among the three groups of patients was identified for potential use as biomarkers.

A newly developed antibody suspension bead array assay allows for a systematic and high-throughput plasma profiling. This microtiter based assay uses antibody-coupled beads for a multiplexed analysis of minute amounts of directly labelled samples. The key requirement of a?nity reagents towards all human proteins is met by the Human Protein Atlas project.

Clinical Evaluation of human embryonic stem cells (hESCs) induced with directed differentiation to gonadotrope cells to cure vasculogenic impotency and to improve coital frequency in males. An open st

This work demonstrates the clinical efficacy, tolerability and safety of patient-syngenic hESC induced with directed differentiation to gonadotrope cells. Hypothalamus transmits gonadotropin releasing factor to pituitary that sets off LH and FSH to Sertoli cell and Seminiferous tubule resulting Leydig cell to produces testosterone. This potential offers a rationale to evaluate hESCs to cure patients with vasculogenic impotency and to improve coital frequency in males.

Five noncovalent peptidic ligands show different affinity rankings in solution and gas phase

Stability of noncovalent complexes of VEGF protein with 5 peptidic ligands is studied. Experiments were conducted in solution (NMR CSP, ITC) and in gas phase (CID TOF MS). Each ligand differs from others in chirality of one amino acid. It was shown, that trend of stability of the studied noncovalent complexes is reversed in the gas phase relatively to the solution. An explanation of this behavior is presented.

Insulin Decreases Transcription of Three Proteins Associated with Lung Surfactant

Our project is partially focused on insulin affecting four proteins associated with lung surfactant. Small and hydrophobic SP-B and S-PC help to spread and stabilize the surfactant layer while large and hydrophilic SP-A and SP-D participate in immune responses. A549 and H441 cell lines were used. It was observed using RealTime PCR that higher doses of insulin lead to decreased transcription of SP-B, SP-C, SP-D, and both isoforms of SP-A.
