To produce functional Hb (haemoglobin), nascent α-globin (αo) and β-globin (βo) chains must each bind a single haem molecule (to form αh and βh) and interact together to form heterodimers. The precise sequence of binding events is unknown, and it has been suggested that additional factors might enhance the efficiency of Hb folding. AHSP (α-haemoglobin-stabilizing protein) has been shown previously to bind αh and regulate redox activity of the haem iron. In the present study, we used a combination of classical and dynamic light scattering and NMR spectroscopy to demonstrate that AHSP forms a heterodimeric complex with αo that inhibits αo aggregation and promotes αo folding in the absence of haem. These findings indicate that AHSP may function as an αo-specific chaperone, and suggest an important role for αo in guiding Hb assembly by stabilizing βo and inhibiting off-pathway self-association of βh.

In this work, a series of Pressure Sensitive Adhesives (PSAs) of poly(n-butyl acrylate-2-ethyl hexyl acrylate- acrylic acid) were synthesized via emulsion polymerization. The PSAs particles were carried out in a semicontinuous process. Synthesis was carried out in two stages of thereaction. In the first, a core of poly(butyl acrylate-co-2-ethyl hexyl acrylate) with a composition of 50/50 wt%/wt % was synthesized, while in the second stage, the core was charged in the reactor as a seed; and was recovered with a poly(butyl acrylate-co-2-ethyl hexyl acrylate-co-acrylic acid) shell. The acrylic acid in the shell was varied between 0, 1, 3 and 5 wt%. The PSAs obtained were characterized by dynamic light scattering and zeta potential. The results of dynamic light scattering showed monodispersed particles with an average particle size of 350 nm, while the zeta potential results decreased as the acrylic acid content increased. The mechanical tests showed that the increase in acrylic acid content in the particle shell improves the adhesion properties. For peel adhesion, the maximum value was reached at 3 wt% of acrylic acid.
