1. Cell Culture and Cell Lines by ECACC
- www.ecacc.org.uk
- Cell Culture and Cell Lines Supplier, ECACC.
- The European Collection of Cell Cultures (ECACC) is a world-wide supplier of authenticated cell culture and cell lines. It has several different collections of cell culture containing cell lines with different characteristics. Cell culture is available in two formats, as frozen cell culture or growing cell lines. ECACC also supplies DNA from cell culture, particularly a series Human genomic control DNA extracted from lymphoblastoid cell culture. Such cell lines are generated by EBV transformation generating immortalised cell culture, which can be used as an infinite source of control DNA. Other cell culture collections include a collection of HLA defined cell lines or a collection of cell culture representing over 800 different genetic disorders. ECACC has recently formed a partnership with Sigma-Aldrich to enhance European distribution of ECACC cell culture. The cell lines are sent directly to customers so that they retain the benefit of ECACC cell culture which are authenticated and mycoplasma free. Other cell culture services are offered by ECACC includes mycoplasma testing of cell lines; a safe deposit facility for cell culture and a EBV transformation service to generate lymphoblastoid cell culture.
2. A Three-Dimensional Interactive Cell

- A Three-Dimensional Interactive Cell.
- Cell Biology has traditionally been taught through a combination of two-dimensional diagrams, blackboard drawings, and microscope labs. With these methods it is difficult for students to get a real understanding of either the topology of the cell or the form of the various organelles. The Virtual Cell project lets the biology student get inside the cell and view 3D models of its structures.
- This project will eventually include two-dimensional animations of cell processes to supplement traditional static textbook illustrations, as well as additional three-dimensional animations, and VRML models of the cell. ...

- A plant cell from the leaf .
- The cell is one of the most basic units of life. ... The cell is the smallest unit of life in our bodies. ... The cell membrane regulates the movement of water, nutrients and wastes into and out of the cell. Inside of the cell membrane are the working parts of the cell. At the center of the cell is the cell nucleus. The cell nucleus contains the cell's DNA, the genetic code that coordinates protein synthesis. In addition to the nucleus, there are many organelles inside of the cell - small structures that help carry out the day-to-day operations of the cell. ... The transcription phase of protein synthesis takes places in the cell nucleus. After this step is complete, the mRNA leaves the nucleus and travels to the cell's ribosomes, where translation occurs. ... Mitochondria (many mitochondrion) are often referred to as the power plants of the cell because many of the reactions that produce energy take place in mitochondria. Also important in the life of a cell are the lysosomes.
- This is because of a unique cellular structure called the cell wall. The cell wall is a rigid structure outside of the cell membrane composed mainly of the polysaccharide cellulose. As pictured at left, the cell wall gives the plant cell a defined shape which helps support individual parts of plants. In addition to the cell wall, plant cells contain an organelle called the chloroplast. ...

- Mouse embryonic stem cell line established.
- Plasma (cell) membrane.
- Each eukaryotic cell has as its boundary to the outside a cell membrane (7. ... The cell or plasma membrane is a lipid bilayer containing proteins, cholesterol, and oligosaccharides that functions as a selective barrier for entry and exit of substances. The plasma membrane, by limiting the transport of some things and facilitating the movement of others helps to maintain the internal environment of the cell, which is different from the extracellular fluid. ...
- Proteins are a very important part of the cell membrane. ... Integral proteins are embedded within the cell membrane and may in fact pass multiple times through the membrane. ... Carbohydrate portions of glycoproteins and glycolipids are found on the external surface of the cell membrane where they are important parts of receptor molecules. ... Most proteins are fixed in place within the cell membrane by interactions with the cytoskeleton. ...

Two different colored pipe cleaners cut at varied lengths to represent chromosomes for assessment (4 chromosomes per cell). ... After a review of cell parts, the teacher would exhibit the onion (or prepared slides) and explain that root tips have been cut for the students to observe. ... This stops cell division. ... During normal cell activity the chromosomes are unwound and too thin to be seen. During cell division, chromosomes thicken, take up stain and can be easily observed. The students should also try to come up with reasons why cells divide (possible answers: to grow, to repair or replace damaged cells, to reproduce, or to differentiate in the cell cycle of multicellular organisms). ... What the students are observing is an ordered process by which the cells divide the chromosomes so that one copy of each goes to each new cell. ... Once all the students have drawings of all the phases of mitosis, ask them to arrange the pictures in a way which would show a logical sequence of cell division. ... Students are to make a model of a cell which is in the process of mitosis and cell division. They should draw on their paper the border of a cell which is dividing.
