What primary human diseased airway cells does Lonza offer?

Lonza's current portfolio for human diseased airway cells includes:- Bronchial Epithelial Cells- Lung Fibroblasts- Bronchial Smooth Muscle Cells...from asthmatic and COPD donors and if available from donors with Cystic fibrosis.An overview of...

What buffer conditions give best resolution for agarose electrophoresis?

For small DNA fragments (<1,000 bp) when recovery is not necessary, we recommend the use of 1X TBE Buffer. Gels made with TBE Buffer give sharper bands than gels made with TAE Buffer. TBE results in better resolution for closely spaced DNA bands....

How is the disease state for Lonza’s diseased airway cells determined?

The tissue received for all of Lonza’s diseased airway cells are obtained from donors which were diagnosed by an accredited physician prior to death. Frequently, Lonza will obtain information on medications taken related to the disease which will...

How does Lonza test for quality of the diseased airway cells?

Diseased Bronchial Epithelial Cells are characterized by morphology through serial passage and some are tested for differentiation using B-ALI™ Differentiation protocols, these are tested for TEER levels, ciliogenesis, and mucin production. Diseased...

How should I cast my agarose gels to get the best resolution?

We usually cast agarose gels 3 mm to 4 mm thick. The gel volume needed can easily be estimated by measuring the surface area of the casting chamber, then multiplying by the gel thickness. Thinner gels can be cast on GelBond™ Support Film, and/or cast...

What medium do you recommend for the diseased airway cells?

The recommended medium for diseased cells is the same as for normal cells. BEGM™ for Diseased Bronchial Epithelial Cells, some lots are guaranteed in B-ALI™ Media. SmGM™-2 Medium is recommended for Diseased Bronchial Smooth Muscle Cells. FGM™-2...

The DNA bands on my agarose gel are sometimes wavy, but usually only in one or two lanes. What causes this?

Dried agarose on the comb teeth is a frequent cause of this problem. Prior to casting your gel, check the comb teeth for residual dried agarose.If not removed, this will attach to the newly cast agarose and fracture the well upon comb removal. This...

What growth factor is pertinent in chondrogenic differentiation of mesenchymal stem cells?

TGF-B3 has worked best in our hands so that is what we recommend.

What donor characteristics are available for the diseased airway cells?

Most Clonetics™ Primary Cells have donor information on the Certificate of Analysis (CoA). This information usually includes age, sex, and race. Sometimes additional information may be obtained by contacting Lonza Scientific Support - if this...

Are there any substitutions that can be used in place of the HSA in the freezing media for hMSC's (Human Mesenchymal Stem Cells)?

Cryopreservation may compromise cell quality and performance. Lonza CANNOT guarantee performance of Clonetics™ & Poietics™ Cells that have been cryopreserved outside of Lonza. To avoid loss of cells and forfeiture of your warranty, we recommend...
