What is in your ReagentPack Subculturing Reagents Kit (CC-5034)?

The ReagentPack™ Subculturing Reagents Kit is composed of three components: - 100 ml of HEPES Buffered Saline Solution, - 100 ml of Trypsin/EDTA- 100 ml of Trypsin Neutralizing Solution (TNS).

Do I need to heat inactivate the FBS contained in the SingleQuots Kit?

No, we do not recommend heat inactivating the FBS provided in the SingleQuots™ Kit. Heat inactivating the serum can alter cell performance and denature essential components in the serum.

Do I need a special media or protocol for culturing the Clonetics and Poietics Diseased Cells?

No, all of our diseased cells are isolated, expanded, and tested in the same media and using the same protocol as the normal counterpart cells.

How to prepare a BulletKit Medium?

The SingleQuots™ Kit provided in the BulletKit™ Media have been premeasured for the bottle of basal medium also provided in the kit. For most BulletKit™ Media, simply thaw the SingleQuots™ and add them to the bottle of basal medium. The complete...

How do I cryopreserve Lonzas primary cells? What media cocktail are Lonzas primary cells cryopreserved in?

Please be aware that 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...

Can an alternate to the 5-bromo-2'-deoxyuridine (BrdU) be used to control the growth of fibroblasts when culturing rat cardiac myocytes?

At this time, we can only recommend the use of BrdU for controlling the growth of fibroblasts.When developing this product, we tried using cytosine beta-arabino furanoside (CAF) to inhibit fibroblast growth. While CAF successfully inhibited the...

What concentration of Trypsin/EDTA do you recommend for subculturing primary cells?

For most cell types, Lonza recommends the Trypsin/EDTA provided as one of the components in our ReagentPack™ Subculturing Reagents Kit (CC-5034).The concentration of this solution is proprietary.

Can I get a Material Data Safety Sheet (MSDS) for my Lonza endotoxin detection Bacterial Endotoxin Testing (BET) kit, LAL or PyroGene Recombinant Factor C (rFC), and/or my accessory products?

All of our endotoxin detection products have been evaluated and deemed non-hazardous in accordance with 29 CFR 1910.1200, the Hazard Communication Standard, based on the percentage quantities of its constituents. Therefore, none of our endotoxin...

Can an alternate to the nitrocellulose be used as an extracellular matrix when culturing rat cardiac myocytes?

Lonza’s rat cardiac myocytes can also be cultured on fibronectin or laminin. Nitrocellulose was selected as the recommended substrate for its convenience and ease of use.

When running a Lonza Bacterial Endotoxin Test (BET), LAL or PyroGene Recombinant Factor C (rFC), endotoxin detection assay why should I use glass accesory products instead of plastic?

Endotoxin adheres to plastic surfaces more strongly than to glass surfaces. Therefore, we recommend that you use only borosilicate glass dilution tubes when preparing your Control Standard Endotoxin (CSE) dilutions. In some cases, certain plastics...
