Application

Leukocyte Alkaline Phosphatase (LAP) kits are intended for the qualitative demonstration of alkaline phosphatase activity in white blood cells.
Peripheral blood or bone marrow preparations are fixed to a microscope slide. The film is then incubated in a mixture of naphthol AS-BI alkaline solution with fast red violet LB. The resulting insoluble diffuse, red dye deposit indicates sites of alkaline phosphatase activity.

p38 MAPK activity plays an important role in several steps of the osteoblast lineage progression through activation of osteoblast-specific transcription factors and it is also essential for the acquisition of the osteoblast phenotype in early development. Although reports indicate p38

The purpose of this study was to develop a paradigm for quantitative molecular imaging of bone cell activity. We hypothesized the feasibility of non-invasive imaging of the osteoblast enzyme alkaline phosphatase (ALP) using a small imaging molecule in combination with

Stem cell differentiation involves critical changes in gene expression. Identification of these should provide endpoints useful for optimizing stem cell propagation as well as potential clues about mechanisms governing stem cell maintenance. Here we describe the results of a new

Histone H3 lysine 9 methylation has been shown to be a critical barrier to efficient cell reprogramming. This discovery allows the assessment of the cell pluripotency state by considering the extent of H3K9 methylation vs. acetylation at the same position.

The development of a new family of implantable bioinspired materials is a focal point of bone tissue engineering. Implant surfaces that better mimic the natural bone extracellular matrix, a naturally nano-composite tissue, can stimulate stem cell differentiation towards osteogenic lineages
