Measurement of density and chemical concentration using a microfluidic chip.

A new microfluidic product for measuring fluid density, specific gravity and chemical concentration has been developed. At the core of this lab-on-a-chip sensor is a vacuum-sealed resonating silicon microtube. Measurements can be made with under a microliter of sample fluid, which is over 1000x less than is conventionally required.

Characterization and localization of fluorescent Pseudomonas cold shock protein(s) by monospecific polyclonal antibodies.

Cold shock protein (CSP) from Pseudomonas fluorescens MTCC 103 and cold resistant protein (CRP) from its mutant CRPF8 of 14 and 35 kd, respectively were purified to homogeneity by HPLC. Polyclonal antibodies were raised against these proteins and the expression level was checked at different temperatures, i.e.
