How do I promote keratinocyte terminal differentiation towards corneocytes?

Keratinocyte differentiation can be induced by increasing the concentration of calcium and/or by adding serum to the media. Cells should be initially plated using the standard culture media and conditions and allowed ample time to recover from...

How do I prevent keratinocyte terminal differentiation towards corneocytes? Can Lonzas keratinocytes be cultured without calcium?

Keratinocyte differentiation can be induced by calcium in the culture media. As such, lowering the calcium concentration in a serum free media will greatly lower the chances keratinocytes terminally differentiating towards corneocytes. While Lonza...

How should I properly heat my Lonza QCL-1000 Endpoint LAL Bacterial Endotoxin Test (BET) Assay?

Incubation is another area where assay performance can be affected. We recommend the use of a dry bath and heat block combination that is capable of maintaining 37 ±1 °C. The temperature should be monitored with a calibrated thermometer and checked...

Lonza’s luminescent assays (including MycoAlert® Mycoplasma detection assay, MycoAlert® PLUS Mycoplasma detection assay, MycoAlert® Control set, ToxiLight® Non-Destructive Cytotoxicity Assay, and ViaLight® Plus Cell Proliferation...

How should I handle the reconstituted Lonza LAL PYROGENT Gel Clot Bacterial Endotoxin Testing (BET) Reagent?

Rehydrated LAL reagent may be stored for as long as 24 hours, but it must be kept at 2-8 °C. Do not pre-incubate lysate in the LAL test tubes before adding samples to them. This is not necessary and may cause sensitivity loss in the LAL reagent. If...

Why cant I obtain a Certificate of Analysis (COA) for a component within a SingleQuot Kit?

Lonza’s SingleQuot™ Kits contain various supplements and growth factors (such as fetal bovine serum, antibiotics, or hydrocortisone). While each supplement and growth factor will have its own catalog and lot number, each supplement and growth factor...

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)....
