Why Horse Serum Is Used For Cell Culture?

Horse serum is sometimes preferred over other types because it tends to have a higher protein content than fetal bovine serum; in addition, its trace element concentration is lower. It is often chosen for assays involving neuronal cells.

Which is the most effective serum used in cell culture?

FBS
FBS is the liquid portion that remains after blood is drawn from bovine fetus coagulates. It’s the most widely used serum supplement for in-vitro cell culture (for eukaryotic cells). Additionally, it plays a vital role in the research of human and veterinary vaccines and has applications in stem cell research.

Why do PC12 cells need horse serum?

It is currently unclear what role the horse serum plays in PC12 cell culture, but given that PC12s are progenitor cells and can differentiate along both chromaffin and sympathetic neuronal lineages [1], horse serum may preserve the progenitor status of these cells.

Why is serum used in tissue culture?

Why do cell and tissue cultures need serum? Serum is added as a supplement to culture media at a concentration of 2-10% to provide a mixture of nutritional, hormonal, growth and attachment factors.

Why fetal calf serum is used in cell culture?

Fetal bovine serum (FBS) is a universal growth supplement of cell and tissue culture media. FBS is a natural cocktail of most of the factors required for cell attachment, growth, and proliferation, effective for most types of human and animal (including insect) cells.

Which serum is used for animal cell culture?

fetal bovine serum
Culture serum
are available and utilized, fetal bovine serum (FBS) remains the most universally employed. FBS contains a sparse amount of gamma globulin, higher levels of growth factors, and fewer complement proteins than both calf and adult bovine serum.

Can cells grow without serum?

Note that some cell types can be cultured in the complete absence of serum, while others will need other factors added to replace the role of serum in the media.

What is horse serum used to treat?

Equine hyperimmune serum is used as antivenom to treat poisonous bites or stings from various snakes, spiders, jellyfish, stonefish, and scorpions [11].

Does horse serum need to be heat inactivated?

Horse serum is available in both a heat inactivated and non-heat inactivated format. HI serum is heated for 30 minutes at 56°C while mixing to inactivate the complement.

What type of cells are PC12 cells?

PC12 cells are a type of catecholamine cells that synthesise, store and release norepinephrine and dopamine. There are significant morphological and growth differences between the PC12 and PC12 Adh cell lines.

What is the main function of serum?

The human serum is a circulating carrier of exogenous and endogenous liquids in the blood. It allows substances to stick to the molecules within the serum and be buried within it. Human serum thus helps in the transportation of fatty acids and thyroid hormones which act on most of the cells found in the body.

Why is serum used instead of blood?

The serum is the liquid or undiluted part of the blood, which lacks clotting factors. Hence, it is formed after blood coagulation. The serum helps in the diagnosis of diseases such as blood pressure, sugar, cholesterol, etc.

What is the purpose of serum sample?

Serum is used in numerous diagnostic tests as well as blood typing. Measuring the concentration of various molecules can be useful for many applications, such as determining the therapeutic index of a drug candidate in a clinical trial. To obtain serum, a blood sample is allowed to clot (coagulation).

Why heparin is used in cell culture?

Highlights. Heparin is a common cell culture adjuvant for the expansion of human stem cells. Heparin affects multiple cell signaling components that can alter human mesenchymal stem cell responsiveness. Heparin exerts donor-dependent effects on gene expression and proliferation of human mesenchymal stem cells.

Why trypsin is used in cell culture?

Prior to seeding a synthetic surface, ECs are usually treated with the proteolytic enzyme, trypsin, which cleaves proteins at the carboxyl side of the basic amino acids lysine and arginine, in order to remove cells from their culture substrate and hence be used for further applications [10].

What is DMSO in cell culture?

As a cryoprotective agent, DMSO is added to cell freezing medium to prevent the formation of ice crystals during the freezing process, otherwise cells would be destroyed and dead. It is commonly used in cell banking. DMSO has a low toxicity to cells.

Can we use human serum in cell culture?

Discussion: Human serum can support proliferation and differentiation of hMSC in vitro and can maintain their bone forming capacity in vivo. The use of human serum in cell cultures of hMSC intended for cell-based therapy is preferable.

Why serum free media is used in animal cell culture?

Serum-free media are media designed to grow a specific cell type or perform a specific application in the absence of serum. The use of serum-free media (SFM) represents an important tool, that allows cell culture to be done with a defined set of conditions as free as possible of confounding variables.

Is the most frequently used serum in animal cell culture media?

Fetal bovine serum is the most common supplement in animal cell culture media.

Is serum inside or outside cell?

However, the term “serum test” is specific – it means something measured outside the cells (extracellular) in the plasma portion of blood. For the purposes of micronutrient testing, serum testing is practically synonymous with plasma testing.

What stimulates cell growth?

Some extracellular signal proteins, including PDGF, can act as both growth factors and mitogens, stimulating both cell growth and cell-cycle progression. This functional overlap is achieved in part by overlaps in the intracellular signaling pathways that control these two processes.
