an introduction to cell division

An Introduction to Cell Division

Cell division is the process by which a parent cell divides and gives rise to two or more daughter cells. It is a means of reproduction for single-cell ...

cell cycle analysis

Cell Cycle Analysis

Cell cycle refers to the set of events through which a cell grows, replicates its genome, and ultimately divides into two daughter cells through the ...

live cell imaging of mitosis

Live Cell Imaging of Mitosis

Mitosis is a form of cell division in which a cell&#8217;s genetic material is divided equally between two daughter cells. Mitosis can be broken down into ...

an introduction to cell motility and migration

an-introduction-to-cell-motility-and-migration

An Introduction to Cell Motility and Migration

Cell motility and migration play important roles in both normal biology and in disease. On one hand, migration allows cells to generate complex tissues ...

the transwell migration assay

The Transwell Migration Assay

Cells migration in response to chemical cues is crucial to development, immunity and disease states such as cancer.  To quantify cell migration, a simple ...

invasion assay using 3d matrices

Invasion Assay Using 3D Matrices

The extracellular matrix (ECM) is a network of molecules that provide a structural framework for cells and tissues and helps facilitate intercellular ...

an introduction to endocytosis and exocytosis

an-introduction-to-endocytosis-and-exocytosis

An Introduction to Endocytosis and Exocytosis

Cells can take in substances from the extracellular environment by endocytosis and actively release molecules into it by exocytosis. Such processes ...

cell-surface biotinylation assay

Cell-surface Biotinylation Assay

A cell can regulate the amount of particular proteins on its cell membrane through endocytosis, following which cell surface proteins are effectively ...

fm dyes in vesicle recycling

FM Dyes in Vesicle Recycling

FM dyes are a class of fluorescent molecules that has found important use in studying the vesicle recycling process. By virtue of a chemical structure, ...

an introduction to cell metabolism

An Introduction to Cell Metabolism

In cells, critical molecules are either built by joining together individual units like amino acids or nucleotides, or broken down into smaller ...

the atp bioluminescence assay

The ATP Bioluminescence Assay

In fireflies, the luciferase enzyme converts a compound called luciferin into oxyluciferin, and produces light or &#8220;luminescence&#8221; as a result. ...

detecting reactive oxygen species

Detecting Reactive Oxygen Species

Reactive oxygen species are chemically active, oxygen-derived molecules capable of oxidizing other molecules. Because of their reactive nature, there are ...

an introduction to cell death

An Introduction to Cell Death

Necrosis, apoptosis, and autophagic cell death are all manners in which cells can die, and these mechanisms can be induced by different stimuli, such as ...

the tunel assay

The TUNEL Assay

One of the hallmarks of apoptosis is the nuclear DNA fragmentation by nucleases. These enzymes are activated by caspases, the family of proteins that ...

annexin v and propidium iodide labeling

Annexin V and Propidium Iodide Labeling

Staining with annexin V and propidium iodide (PI) provides researchers with a way to identify different types of cell death&#8212;either necrosis or ...

cell biology

Cell Biology

This collection provides a glimpse into the field of cell biology and profiles five important cellular phenomena: cell division; motility; endocytosis and exocytosis; metabolism; and cell death.
