What are J774A 1 cells?

J774A. 1 is a cell line isolated in 1968 from the ascites of an adult, female patient with reticulum cell sarcoma. This cell line can be used in immunology research. Animal cells. Mus musculus, mouse.

What is J774 cell line?

Abstract. Macrophage cell lines like J774 cells are ideal model systems for establishing the biophysical foundations of autonomous deformation and motility of immune cells.

How do you culture a J774 cell?

Take the culture dish with 90-95% cell confluency, Remove the old media and give a PBS wash. Then add 2 mL of media and dislodge the cells with the help of a cell scraper. Take the dislodged cells in a 15 mL falcon tube, add 8 mL of media, then pellet down the cells.

What are RAW cells?

The RAW 264.7 cells are monocyte/macrophage-like cells, originating from Abelson leukemia virus transformed cell line derived from BALB/c mice. These cells are being described as an appropriate model of macrophages. They are capable of performing pinocytosis and phagocytosis.

What are primary macrophages?

Definition and function. Macrophages are tissue-resident professional phagocytes and antigen-presenting cells (APC), that form as a result of the differentiation of circulating peripheral blood monocytes.

What is murine macrophage?

Macrophages are mononuclear phagocytes that are widely distributed throughout the body. These cells can contribute to development and homeostasis and participate in innate and adaptive immune responses.

How do I wash cells with PBS?

Wash cells twice in PBS. To wash cells, resuspend the cell pellet in PBS, centrifuge at 350 x g for 5 minutes, and gently pour off supernatant.

How do you detach a raw cell?

All Answers (5) One thing people usually do is to add PBS, leave the plates in the incubator for 10 minutes and then tap the edges of the plate vigorously. This should detach most of the cells. You could scrape the remaining adherent cells gently with a scraper and they should come off easily.

How do you differentiate C2C12 cells?

Differentiation of C2C12 cells is achieved by replacing GM to differentiation media, DM [DMEM—high glucose no sodium pyruvate (Gibco), 2% horse serum (Gibco), 1% glutamine (Gibco), 1% pen/strep (Gibco)]. After 24 h in DM, fused cells should be visible. DM should be changed every 48 h.

Where do C2C12 cells come from?

C2C12 is a subclone from a myoblast line established from normal adult C3H mouse leg muscle1. The original cell line, C2, was obtained by Yaffe and Saxel in 1977 by establishing primary cultures from the thigh muscle of 2 month old normal mice, 70 hours after crush injury2.

What is the difference between M1 and M2 macrophages?

M1 macrophages, also called classically activated, respond to stimuli such as LPS, IFN-γ, and are important producers of pro-inflammatory cytokines. M2 macrophages, also called alternatively active respond to stimuli such as IL-4 or IL-13, are producer of anti-inflammatory cytokines.

Why is EDTA used in cell culture?

EDTA act as a metal chelator, which is added to trypsin solutions to enhance activity. EDTA is added to remove the calcium and magnesium from the cell surface which allows trypsin to hydrolyze specific peptide bonds. The principle reason of using the EDTA along with trypsin is to remove cell to cell adhesion.

Why is PBS used for washing?

PBS has many uses because it is isotonic and non-toxic to most cells. The pH of PBS is set to be 7 to 7.6, so it can maintain the constant pH of the cells. PBS is an isotonic and non-toxic solution which keeps tissue intact preventing them from rupturing.
