4 protocols using fibronectin fn from human plasma

1

Fibronectin Adsorption on PVDF

Check if the same lab product or an alternative is used in the 5 most similar protocols
Fibronectin (FN) from human plasma (Sigma-Aldrich, St. Louis, MO, USA) was adsorbed onto the PVDF samples. The biomaterials were immersed in a FN solution of 20 μg/mL for 1 h under constant shaking. After protein adsorption, the samples were rinsed in saline solution to eliminate the non-adsorbed protein.

All of the reagents were used without further purification. Fibronectin (FN) from human plasma, gelatin (G), Dulbecco’s modified eagle medium (DMEM), fetal bovine serum and the cell culture insert with a 0.4 or 3 µm pore membrane was purchased from Sigma-Aldrich (MO, USA), Wako Pure Chemical Industries (Osaka, Japan), Nacalai Tesque (Kyoto, Japan), Life Technologies (CA, USA) and Corning (NY, USA), respectively. Normal human cardiac fibroblasts (NHCFs), normal human cardiac microvascular endothelial cells (HCMVECs), cardiac fibroblast growth medium (FGM-3) and endothelial growth medium (EGM-2 MV) were further purchased from Lonza (NJ, USA).

Layered Fibronectin-Gelatin Coating of Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
Fibronectin (FN) from human plasma (MW = 4.6 × 105 Da) was purchased from Sigma‐Aldrich (St. Louis, MO, USA), and gelatin (G) (MW =1.0 × 105 Da) was purchased from Wako Pure Chemical Industries (Osaka, Japan). All chemicals were used without purification. For LbL filtration, 2.5 mL of a solution containing 0.2 mg/mL FN and G in 50 mM Tris–HCl (pH =7.4) were added to three wells of a 6‐well plate. NHDFs dissociated with 0.1% trypsin were resuspended in 500 µL of 0.2 mg/mL FN and G/Tris–HCl solution and transferred to a 6‐well plate culture insert with a membrane pore size of 0.4 µm (Corning, Inc., Corning, NY, USA). The insert was placed in the well containing the FN and G/Tris–HCl solution and alternately incubated for 1 min in a shaking incubator (SI‐300; As One Co., Osaka, Japan) and washed. To collect the coated cells at each step, the insert was transferred to an empty well and shaken horizontally at 1.1 g to filter the cell suspension.2

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.
