CFBE and 16HBE Cell Culture Protocol

Check if the same lab product or an alternative is used in the 5 most similar protocols
CFBE cells (CFBE41o-) and human bronchial epithelial cells (16HBE14o-)38 (link) were grown with LHC-8 media (Invitrogen) with 10% FBS, 1X antibiotic antimycotic (Gibco), and tobramycin 40 mg per 500 mL (Sigma). Once grown to confluence, cells were trypsinized by first washing with 0.05% trypsin, then adding 0.25% trypsin for 5 minutes, and harvesting with RPMI medium with 10% FBS. Cells were frozen in 5% DMSO in culture medium as necessary. Nanoparticles were resuspended in culture media by vigorous vortexing and water sonication, then added directly to cells at concentrations of 2 mg/mL/1×10^6 cells (corresponding to approximately 10^9 PNA/DNA molecules delivered to each cell assuming 100% efficiency).
To test primers, a 712 base pair region of the CFTR gene, with either the F508DEL or corrected sequence (including our silent modifications), was cloned into plasmids. PCR reactions were first tested on plasmids. Gradient and step-down PCR at varying conditions was performed to ensure that F508del primers only amplified the F508del plasmid, and the donor-specific primers only amplified the donor-sequence-containing plasmids. Primers are included in Supplementary Table 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.
