Protocol for Freezing Cells When you have started a new cell line it is a good policy to freeze down a good portion of the cells for use at a later date. For example, if you thaw a vial of COS cells to carry the cell line you will eventually split the cells into 10-15 plates. Once you have done this freeze down a Clean Cell Culture - University of Florida Transfer cell suspension from the cryovial into a 15mL conical tube containing 10 mL of DMEM supplemented with FBS. Frozen cell stocks contains cryopreservant such as dimethyl sulfoxide (DMSO), which has negative and harmful effect on cells, therefore it is important to wash the cells from them before you propagate them.

It outlines critical Freezing Cells - Harvard University Freezing Cells Regular (MCF-10a) cells: 70% growth media 20% horse serum 10% DMSO for a 20 ml stock: 14 ml growth media 4 ml horse serum 2 ml DMSO -store at 4 degrees -1 plate = 1 cryovial = 1ml of freezing media - trypsinize cells as usual, then resuspend in 1 ml freezing media GPG Packaging cells: How Safe is the Cryoprotectant Dimethyl Sulfoxide (DMSO)? The chemical is associated with possible toxicity and a range of serious side effects. Also, prolonged exposure to dimethyl sulfoxide directly impacts cellular function and growth. One of our molecular biologists explained that she has used DMSO to preserve cell lines for research, but gets rid of the DMSO as soon as possible.
Freshly prepared freezing media of 20% FBS, DMSO. I've heard the quality of the DMSO affects the viaiblity, but haven't ever tested that. I put them straight into the
growing cells, ECACC experts advise you to prepare your own frozen stock of If DMSO is not suitable, an alternative, such as glycerol, is specified in the cell re-suspended with media supplemented with 20% foetal bovine serum (FBS) The cryopreservation medium for A-375 is the complete growth medium (DMEM + 10 % (v/v). FBS) containing 5 % (v/v) DMSO) (ATCC cat. no. 4-X). Page 5. SOP: The basics of cell culture for patient-derived melanoma cell lines share certain Resuspend the cell pellet in cold freezing media (90% FBS/10% DMSO solution) at a density of 1 x 106 cells/mL. or each time a frozen seed stock is made. appropriate protective agent (e.g., DMSO or glycerol) and stored at temperatures below. –130°C for rapid expansion of cell stocks, propagation of baculovirus stocks, and production of F-10, 15% horse serum, and 2 .5% FBS. BALB/3T3.
5.2 Spin cells down at 1000 rpm for 5 minutes, and resuspend in FBS: DMSO 90:10 ratio. Add FBS first, as the DMSO is harmful to the cells. A typical cell concentration is between 4x106-6x106 cells/ml. 5.3 Aliquot amount calculated into 2 mL Corning cryovials, labeled with cell name, passage number, and date on each cryovial.
24 Dec 2009 Since hES cells are very sensitive to the stresses of freezing and thawing, technique for rapidly thawing hES cells from liquid nitrogen stocks, plating them FBS, 20% hES cell culture medium, and 20% DMSO) to the cells. Cell Freezing Medium–II contains 90% Fetal Bovine Serum and 10% DMSO ( dimethyl sulfoxide). This cryopreservation medium is supplied as a ready-to-use

Surviving the Big Chill: Freezing and Thawing Mammalian Cells
Slowly, while gently shaking the tube, add the appropriate amount (0.5 mL per cryovial) of 2X hES cell freezing medium (60% defined FBS, 20% hES cell culture medium, and 20% DMSO) to the cells. Once the freezing medium is added, pipet the solution extremely gently one to two times to mix. Dimethyl sulfoxide - Wikipedia Dimethyl sulfoxide (DMSO) is an organosulfur compound with the formula (CH 3) 2 S O. This colorless liquid is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water. It has a relatively high boiling point. Silly question: is DMSO sterile by itself, to add it to ... Silly question: is DMSO sterile by itself, to add it to cells? - Lab stock bottle could be used? (Aug/22/2005 ) I just wonder, could i use for the purpose of cell freezing DMSO, which is standing on the lab shell, or I should buy a new bottle and to use it only for cell culture, or I could sterilize DMSO?
