7 product FAQs found

Can I isolate total RNA (including miRNA) using the LeukoLOCK Total RNA Isolation System?

Yes. You will need to follow the alternate protocol, available in the following link.

Can I use heparin for blood collection instead of EDTA when using the LeukoLOCK Total RNA Isolation System?

We have processed blood stored with heparin with the LeukoLOCK Total RNA Isolation System. The RNA looks fine. But we have not tested it for any downstream applications. We discourage your use of heparin, as heparin notoriously inhibits downstream applications such as RT-PCR.

Is the LeukoLOCK Total RNA Isolation System compatible with PAXgene tubes?

No, they are based on different chemistries.

Can I use the LeukoLOCK Total RNA Isolation System for monkey or rodent blood?

The LeukoLOCK Total RNA Isolation System has been tested only for human blood.

Can I use the LeukoLOCK Total RNA Isolation System with less than 3 mL of human blood?

No. The kit has not been validated for less than 3 mL of human blood. It is best to use 9-10 mL blood.

What is the typical RNA yield and quality when using the LeukoLOCK Total RNA Isolation System?

RNA yield is typically 10-20 µg from 10 mL of blood. RNA quality depends on the quality of the blood. Typically, the RNA integrity number (RIN) value is around 9, and the 28S/18S ratio is around 1.5.

What are the advantages of using the LeukoLOCK Total RNA Isolation System?

RNA recovered using the LeukoLOCK Total RNA Isolation System typically contains less than 10% of the amount of reticulocyte-derived alpha- and beta-globin mRNAs present in typical mRNA samples from unfractionated whole blood. The isolated RNA is specially suited for gene expression profiling, as it contains a lower proportion of globin mRNA. We sell LeukoLOCK Fractionation and Stabilization Kit (Cat. No. AM1933) for blood collection and stabilization. You can then use LeukoLOCK Total RNA Isolation Kit (Cat. No. AM1934) to isolate RNA stabilized on the LeukoLOCK filters. Cat. Nos. AM1934 and AM1933 are available together, packaged in a single kit as the LeukoLOCK Total RNA Isolation System (Cat. No. AM1923).
