Where is Lonza's fresh bone marrow collected from?

The bone marrow is collected from the iliac crest.

When performing a Lonza Bacterial Endotoxin Test (BET), LAL or PyroGene Recombinant Factor C (rFC), endotoxin detection assay what pH should my sample be? What should I adjust it with?

Our endotoxin detection assays are optimized to work with samples with a pH range of 6-8. If the pH of your sample falls outside of this range you can adjust it with a buffer, or HCl or NaOH. Make sure the buffer you are using is endotoxin free by...

What is the difference between each of the types of HUVECs that Lonza offers?

When choosing between the various types of HUVECs that Lonza offers, the choice can be made by answering the following questions:What media do you intend to culture the cells in?Do you require pooled or single donor cells?Do you require additional...

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...

For cultivation of Smooth Muscle Cells - Can the insulin be left out of the SmGM-2 Media?

Yes, insulin can be left out of the SmGM™-2 media for as long as 1-3 passages.Insulin is beneficial to the cells for long term growth (ie. 4 - 5 passages), however smooth muscle cells do survive quite well short term without insulin.Insulin is not a...

What type of heparin is used with fresh bone marrow?

Lonza uses sodium heparin as the anticoagulant at a final concentration of 100 units/mL.

What are the advantages of the Lonza Bacterial Endotoxin Test (BET), LAL or PyroGene Recombinant Factor (rFC), endotoxin detection assays over the rabbit test?

Lonza LAL and PyroGene™ rFC Endotoxin detection assays are faster, have greater sensitivity, show less variability,, are less expensive, and are an alternative to animal model testing. These assays allow higher throughput and can also be automated on...

Is Lonza's fresh bone marrow filtered?

The fresh bone marrow is filtered only if visible clots are present. If the technical assistance notices clots in the marrow, they pour the marrow over a filter which removes the clot from the aspirate. No other manipulation of the product takes...

Where are Lonzas Normal Human Osteoblasts (NHOst) cells isolated from?

Lonza’s Normal Human Osteoblasts (NHOst) are isolated by explant, and the tissue is from the spongy section of the bone head of the ribs, femur, or tibia.

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...
