2.8 mm Stainless Steel Grinding balls, Pre-filled tubes (50 count)

2.8 mm Stainless Steel Pre-Filled Tubes may be used to lyse a wide variety of samples, including soft animal tissues (liver, brain), fibrous animal tissues (muscle, heart, lung), plant leaf and stem samples, and fungal thalli (e.g., mushrooms).

The grinding balls have been used in the homogenization of mouse brains for HPLC-MS/MS analysis to investigate how different methods of nicotine administration affect the ability of female and male mice to discriminate nicotine from saline. Mouse lung samples have been homogenized using 2.8 mm Stainless Steel Grinding Balls for the detection of viral RNA as well as for the extraction and analysis of mouse hair corticosterone. They have also been used in the extraction of DNA from mucosal and submucosal samples from resected intestinal tissues from Crohn's disease and controls for sequencing. RNA extractions from human adipose-derived mesenchymal stem cells were also performed using these grinding balls. In entomology, these grinding balls are used to homogenize Drosophila flies and cockroaches for RNA extractions and quantitative reverse transcription PCR (RT- qPCR) to investigate whether these domestic insects can mechanically transmit SARS-CoV-2.

Stainless steel grinding balls are resistant to tarnishing and may be retrieved with a magnet. Stainless steel is a very dense grinding medium, and small 2.8 mm can be used with 2 ml disruption tubes to effectively homogenize resilient tissues.   All of OPS Diagnostics’ grinding balls and satellites are ready-to-use, having been treated to remove residual oils and contaminants prior to packaging.

Pre-Filled Tubes are a convenient solution for labs seeking time savings by no longer requiring researchers to weigh, fill and QC individual tubes.  They are available in 2 mL skirted (i.e., self-standing) or unskirted polypropylene tubes to ensure compatibility with most tube homogenizers. Clear screw caps with O-rings included.
