Fatty acid free serum albumin

Manufactured by Merck Group
Sourced in Morocco

Fatty acid-free serum albumin is a lab reagent used as a stabilizer and carrier protein in various biochemical and cell culture applications. It is derived from bovine serum and has been processed to remove any fatty acids. This product provides a source of high-purity albumin without the potential interference from bound lipids.

Epididymal Fat Pad Glycerol Release

Check if the same lab product or an alternative is used in the 5 most similar protocols
Epididymal fat pads were surgically removed from male mice and washed
with ice-cold PBS. Fat pads (100 mg, n = 4/mouse) were preincubated for 1 h in
140 μl of DMEM (Life Technologies) containing 2% fatty acid-free serum
albumin (Sigma-Aldrich). Subsequently, fat pads were incubated in 250 μl
of KRH buffer (125 mM NaCl, 5 mM KCl, 1.8 mM CaCl2, 2.6 mM MgSO4, 5 mM HEPES, pH
7.2) plus 2% BSA (fatty acid free) for 2h at 37°C. Free glycerol content
was quantified for each sample in the medium using the Free Glycerol
Determination Kit (Wako Diagnostics). Glycerol release from each sample was
normalized to the weight of each fat pad.

Mammary fat pads were surgically removed from 16-week-old MMTV-rtTA/TRE-TAZ4SA or wild-type mice and washed with ice-cold PBS. Mammary Fat pads (n = 6) were pre-incubated for 1 h in 140 µl of DMEM (Life Technologies, MA) containing 2% fatty acid-free serum albumin (Sigma-Aldrich, MO). Subsequently, mammary fat pads were incubated in 250 ul of KRH buffer (125 mM NaCl, 5 mM KCl, 1.8 mM CaCl2, 2.6 mM MgSO4, 5 mM HEPES, pH 7.2) plus 2% fatty acid free BSA (Sigma-Aldrich, MO) for 2 h at 37 °C. Free glycerol content was quantified for each sample in the medium using the Free Glycerol Determination Kit (Sigma-Aldrich, MO). Glycerol release from each sample was normalized to the weight of each mammary fat pad.

Ex vivo Mouse Calvarial Culture

Check if the same lab product or an alternative is used in the 5 most similar protocols
Ex vivo organ culture from neonatal mouse calvaria was performed as previously described.28 (link), 29 (link) Bone explants from calvaria were obtained by dissecting parietal bones and frontal bones from 7-day-old Men1flox or Men1Dmp1Cre mice. Calvaria were cut through the sagittal suture and each half was cultured in one well of a 24-well plate. Calvarial halves were treated with 1 μM indomethacin (Sigma-Aldrich) in α-MEM supplemented with fatty acid-free serum albumin (Sigma-Aldrich). After overnight incubation, calvarial halves were treated with CXCL10-neutralizing antibody (20 ng/ml) or IgG in α-MEM supplemented with 10 nM 1,25-dihydroxyvitamin D3 for 5 days. Medium was collected for CTX enzyme-linked immunosorbent assay (ELISA) and calvarial halves were used for RNA isolation or histology.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
