一般描述
Polystyrene-based monodisperse microparticles (size: 2 μm) are a particle size reference standard, ideal for determining the particle size distribution (PSD) profile of test samples.
应用
Used to calibrate, validate and monitor the performance of particle sizers, surface scanning equipment and particle counters.
Monodisperse polystyrene latex particles are also used to investigate their effect on laser-induced breakdown spectroscopy (LIBS) emissions.

Neuregulin-1β (NRG-1) is a membrane-bound or secreted growth and differentiation factor that mediates its action by binding to ErbB receptors. Circulating levels of NRG-1 are characterized by large inter-individual variability with the range of absolute values covering two orders of
