What types of gels do you have for the FlashGel™System?

We offer FlashGel™ Cassettes for DNA, DNA recovery and RNA separation. FlashGel™ DNA Cassettes are available at either 1.2% or 2.2% agarose, and in 12+1 single-tier (13 wells) or 16+1 double-tier formats (34 wells). FlashGel™ DNA Recovery Cassettes...

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...

How long does it take for the fresh bone marrow sample to arrive within the United states from the moment of harvest?

Barring any delays at airport customs, and assuming there are no weather related delays, the sample can be delivered anywhere in the continental United States within 26 hours of collection (same day delivery may be available for local deliveries,...

What are the size of CD34+ Cells?

When resting, they are about 8-10 microns.

When storing my Lonza Bacterial Endotoxin Test (BET), LAL or PyroGene™ Recombinant Factor (rFC), endotoxin detection kit the temperature of my refrigerator/freezer has been out of range. Are my reagents ok to use?

The normal storage temperature for LAL products is 2-8°C. The improper storage of the product for a short period of time should not cause a problem with the performance of the kit as long as the components have not been reconstituted. Lyophilized...

Approximately what size are the Coronary Artery Smooth Muscle Cells (CASMCs)?

Lonza’s R&D estimates that the CASMC’s are around 30 µm in diameter when rounded/in suspension.

How many donors are pooled to create the pooled human cells?

Lonza is offering the following primary cells from single donors and from pooled donors:HUVEC (human umbilical vein endothelial cells)NHEK-neo (human epidermal keratinocytes)HMVEC-dNeo (human microvascular endothelial cells, dermal, neonatal)When...

When would be the optimal time to perform experiments post osteogenic differentiation for human mesenchymal stem cells?

Once the cells have differentiated and started laying down bone matrix, we recommend assaying the cells immediately. If cells begin to delaminate (peel of the culture plate in layers), this would indicate that the cells are embedded in the calcium...

Where are Lonza’s Small Airway Epithelial cells isolated from?

Lonza’s Small Airway Epithelial cells (both normal and diseased) are isolated from the distal portion of the lung in the 1 mm bronchiole area. These cells are isolated from airway tubules 1mm in diameter and smaller. Anything with a diameter greater...

How do I handle my Lonza Control Standard Endotoxin (CSE) for Bacterial Endotoxin Testing (BET)?

Lyophilized E. coli endotoxin should be stored at 2-8°C. Endotoxin solutions are generally very stable upon storage except at more dilute concentrations. Rehydrated E. coli endotoxin should be stored refrigerated only (at 2-8°C and not frozen)....
