By applying improved biomaterials for cell seeding numerous cerebral pericytes were found to express site-specific pericytic aminopeptidase N/pAPN[171].
Each HEV is composed of a prominent perivascular sheath, a thick basal lamina, and a layer of ECs that have a plump morphology [ 22] and express site-specific adhesion molecules and chemokines that promote the trafficking of lymphocytes between blood and lymph node [ 5, 12, 23].
The number of fragile sites detected ranged from 23 in OAF specimen 1 to 12 in OAF specimen 2. Given the intraspecific variability of fragile site expression in mammalian species, we combined all expressed sites into a single species-specific analysis (this was also done for the golden mole and elephant shrew, see below).
To remove the neomycin gene flanked by two FTR sites, BHDflox/+ mice were crossed to FlpeR transgenic mice that express the site-specific recombinase FLP (FLPe).
First, CBS1502 and CBS7001 (the sequenced reference S. uvarum strain) were transformed with plasmids that express the site-specific endonuclease encoding-gene HO under control of the galactose inducible GAL1 promoter and contain one of two different selectable markers (KanMX and HphMX).
In a recent study using transgenic mice expressing recombinant LDL with site specific mutations in apoB, animals with PG-binding-defective LDL developed significantly less atherosclerosis than animals expressing wild type LDL [ 21].
In cells expressing the site-specific cre-recombinase, double-strand breaks occur at both loxP sites.
The cre gene was transiently expressed, mediating site-specific recombination between the chromosomal lox71 and the RE lox on the integration plasmid; this resulted in site-specific integration.
The recombinant CR2 was expressed with an additional C-terminal histidine tag not only for ease of purification but also to allow site specific labeling with technetium [99mTc(CO)3(OH2)3]+.
Approximately 50-60% of breast cancer tumors as well as several breast cancer-derived cell lines express specific binding sites for GnRH [ 26, 27].
They are indivisible and site specific.
