Mononuclear phagocyte progenitor cells derived from femoral and tibial bone marrow are propagated in the presence of M-CSF. This macrophage growth factor is secreted by L929 cells and is used in the form of L929 cell conditioned medium. The progenitor cells proliferate and differentiate through monoblast, promonocyte and monocyte stages before maturing to macrophages. At this time the cells become firmly adherent to the culture vessel. - [Read Isolation and Culture of Mouse Bone Marrow-Derived Macrophages Protocol]
PCR GENOTYPING PROTOCOL. 1) Cut toes of mice at approx. ten days of age and record sex, color, and strain. ... Back to Mouse Genotyping Resources. - [Read PCR GENOTYPING PROTOCOL]
When more than one bait will be used to screen a single library, significant time and resources can be saved by performing the interactor hunt by interaction mating. In this protocol one strain is transformed with library DNA and the transformants are collected and frozen in aliquots. - [Read Performing a Hunt by Interaction Mating Protocol]
Protocol for precision engineering of plant gene loci by homologous recombination cloning in Escherichia coli. Describe the basis for homologous recombination cloning in E. coli, the available tools and resources, together with a protocol for long range cloning and manipulation of an Arabidopsis thaliana gene locus, to create constructs co-ordinately driven by locus-specific regulatory elements. - [Read Precision Engineering of Plant Gene Loci by Homologous Recombination Cloning in E coli Protocol]
Matirgel is considered as basement membrane and generated from EHS sarcoma. Matrigel contains not only basement membrane components (collagens, laminin, and proteoglycans)but also matrix degrading enzymes/their inhibitors and growth factors. Invasion of tumor cells into Matrigel has been used to characterize involvement of ECM receptors and matrix degrading enzymes which play roles in tumor progression. - [Read Protocol for Matrigel Invasion Assays]
