To prepare the samples, the tissue samples were diluted in a buffer.
For initial plating of new dural and scalp samples, the tissue was first grown in biopsy media: DMEM/10% FBS/Glutamax (2 mM /2-Mercaptoethanol (0.1 mM /MEM non-essential amino acids (0.1 mM /antibiotic-antimycotic (1×)/Nucleosides (1×, mM /antibiotic-antimycotic
Since A-Scan grid samples the tissue area densely, in this paper we assume that the magnitude of e i n t e r p is similar to other noise sources in the OCT system and choose not to model its effects.
Many cells were located in the interface region of the enzyme-treated group (Fig. 2a,2b), but despite the apparently normal average vital cell count in the 150-μm broad band in the untreated control samples, the tissue in the interface region was almost acellular (Fig. 2c,2d).
For preparation of membrane and cytoplasmic protein samples, the tissue or cell samples were harvested in hypotonic lysis buffer (10 mM Tris-HCl, pH 7.5, 10 mM NaCl, 0.2 mM EDTA, 1 mM DTT) supplemented with inhibitors (25 mM b glycerol-phosphate, 25 mM NaF, 1 mM Na3VO4, 1 mM PMSF, 1 mM benzamidine,).
For native FTPT and FiTPT and cryopreserved FTPT samples the tissue was put into phosphate buffered saline (PBS) (HyClone, USA) with the addition of 0.2% collagenase I (Serva, Germany), 0.35 mg/mL hyaluronidase (Sigma, USA), 100 U/mL DNase I (Sigma, USA), and 1 mg/mL bovine serum albumin (BSA) (Carl Roth, Germany) and were treated for 30 50 minutes at +37°C (method #1).
For tissue samples, the tissues were formulated into homogenates using saline solution.
To minimize blood content in the tissue samples, the tissues were blotted on absorbent paper.
Traylor said that his finding of suffocation was based entirely on the bruises on Roderius's lips, but he never sampled the tissue to date the injury, a basic test that would have revealed whether the bruises came from the earlier fall in the bathroom, an explanation that he ignored.
Samples of the tissue were sent to two different labs for histopathology.
An n value was assigned for each IHC that indicated scorable samples from the tissue arrays.
