100 and 40 mm nylon cell strainers

Manufactured by BD

The 100- and 40-mm nylon cell strainers are laboratory equipment designed for filtration and separation of cells from cell suspensions. They feature a nylon mesh structure that allows the passage of single cells while retaining larger cellular aggregates.

Mouse and human PDAC tumors and adjacent pancreata were mechanically dissociated and incubated in collagenase (collagenase II for murine tumors, collagenase IV for human tumors, both 5 mg/ml; Worthington Biochemical Corp., Fisher Scientific), DNAse I (0.5 mg/ml; Roche Diagnostics), and Hank’s balanced salt solution (Gibco, Fisher Scientific) for 30 minutes at 37°C. Digestion was then quenched with fetal bovine serum (FBS, Life Technologies), and cells were filtered sequentially through 100- and 40-mm nylon cell strainers (Falcon, Fisher Scientific). Tumors, adjacent pancreata, and lymph nodes were then mechanically disassociated and filtered through 100- and 40-mm nylon cell strainers (Falcon, Fisher Scientific) using PBS with 1% FBS (Life Technologies). Spleens were mechanically dissociated and filtered through 70- and 40-mm nylon cell strainers (Falcon, Fisher Scientific) using PBS with 1% FBS, followed by RBC lysis (RBC lysis buffer, ThermoFisher Scientific). Mouse Fc receptors were blocked with FcεRIII/II-specific antibody (1 μg per 1 × 106 cells; clone 2.4G2, Bio X Cell).

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.
