Morphology bovine serum albumin

However, not only the kinetics but also the morphology of precipitated HAp nanocrystals will be modified by structure-mediated (epitaxial) adsorption of organic constituents such as poly(amino acids) at prominent lattice planes of HAp. For example, adsorption of poly(l-lysine) on (0 0 1) planes causes formation of polycrystalline nanocrystals of HAp whereas adsorption of poly(l-glutamic acid) leads to precipitation of large flat micron-sized single crystals of HAp (Stupp and Braun, 1997). Similar relations have been found in experiments involving adsorption of recombinant human-like collagen (Zhai and Cui, 2006) and bovine serum albumin (BSA) (Liu et al., 2003) on hydroxyapatite surfaces. 

The outer surface morphology of spray-dried trehalose/alcohol dehydrogenase (ADH) powder, with the addition of diflFerent amounts of bovine serum albumin (BSA) or P-lacto-globulin (Lg) is illustrated in Fig. 6.16 (Yoshii et al., 2008). The particle surface appears smooth in the case of AD H alone, no grooves could be found. 

L929 mouse fibroblast cells in this device changed their morphology due to the forces exerted on them. A gradient was created by introducing a standard culture medium with fetal bovine serum (FBS) at one inlet and a serum-free medium at the other. FBS contains proteins, such as serum albumin, that are needed for cell survival, division and growth. The cell density and attachment depended on a combination of sheer stress and FBS concentration [28].
