Matrigel poor in growth factors

Manufactured by BD

Matrigel poor in growth factors is a cell culture matrix that provides a supportive and biologically relevant microenvironment for various cell types. It is a soluble basement membrane extract purified from Engelbreth-Holm-Swarm (EHS) mouse sarcoma cells. This version of Matrigel is formulated with reduced levels of growth factors compared to the standard Matrigel product.

The upper wells of 8-µm-pore-size Boyden chambers were coated with MDSC stained with Hoechst (1:1,000 dilution, Thermo Fisher Scientific) at a density of 103 cells/µL embedded in hydrogel composed by type 1 collagen (2 mg/mL, BD Bioscience) and Matrigel poor in growth factors (2 mg/mL, BD Bioscience) as previously described (58 (link)). HP was used at a concentration of 0.02 to 0.5 mg/mL based on the findings that murine serum levels are between 0.5 and 1.5 mg/mL in normal conditions. After 24 hours, cells were recovered from the lower chamber and were quantified by flow cytometry using a CytoFLEX (Beckman Coulter) and CyteExpert software. Experiments were repeated three times.

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.
