Biology in general and cell biology in particular depend heavily on both chemistry and physics. Simply, cells and organisms follow all the laws of the physical universe, and biology is really just the study of chemistry in systems that happen to be alive. ...

Get DetailsCell biology is an exciting and dynamic area that helps discover the fascinating world of cells. It includes the study of the structure and organization, growth, regulation, movements and interaction of the cells. Cell biology is closely related to other areas of biology such as genetics, molecular biology, and biochemistry.
Get DetailsCentrifugation is a technique that helps to separate mixtures by applying centrifugal force. A centrifuge is a device, generally driven by an electric motor, that puts an object, e.g., a rotor, in a rotational movement around a fixed axis.

And based on a lot of fundamental hard work as well as persistent pursuit during the initial years, we finally made it and had CITOTEST well distinguished from other suppliers of economical products, and CITOTEST obviously became popular as a …
Get DetailsJan 31, 2021 Blood serum is a component of blood plasma. The two are closely related, so they’re often thought to be the same thing. Serum is a fluid found in plasma, and it contains many of the same solid components as blood plasma (such …
Get DetailsJul 12, 2021 Types of Centrifugation. Differential Pelleting (differential centrifugation) It is the most common type of centrifugation employed. Tissue such as the liver is homogenized at 32 degrees in a sucrose solution that contains buffer. The homogenate is then placed in a centrifuge and spun at constant centrifugal force at a constant temperature.
Get DetailsMar 30, 2022 TRIzol Reagent is a ready-to-use reagent used for RNA isolation from cells and tissues.TRIzol works by maintaining RNA integrity during tissue homogenization, while at the same time disrupting and breaking down cells and cell components. Addition of chloroform, after the centrifugation, separates the solution into aqueous and organic phases.
Get DetailsThe cell cycle culminates in the division of the cytoplasm by cytokinesis. In a typical cell, cytokinesis accompanies every mitosis, although some cells, such as Drosophila embryos (discussed later) and vertebrate osteoclasts (discussed in Chapter 22), undergo mitosis without cytokinesis and become multinucleate. Cytokinesis begins in anaphase and ends in telophase, …
Get DetailsThese whisper quiet 24-place microcentrifuges offer an outstanding set of features for a broad range of molecular and cell biology applications in Eppendorf and PCR tubes from 0.2 to 5 mL.
