Description
Each frozen aliquot contains 1 mL of a pure,
titered culture of Aspergillus niger. The
identification of this organism was confirmed by
sequencing the ribosomal DNA locus. The purity
of the culture was monitored by Lactophenol
Cotton Blue staining, Gram staining and by
additional culturing. The titer was performed on a
minimum of two aliquots after freezing. The
freezing medium contains 15% glycerol as a
cryoprotectant. Please see the Certificate of
Analysis for the specific freezing medium used.
Intended Use
Aspergillus niger live, titered microorganisms can be used to determine a limit of detection (LOD), in diagnostic assay development or cross-reactivity studies. When used as a control for nucleic acid tests, the same protocols as those used to amplify clinical specimens should be employed.
More Information
Aspergillus niger is a biosafety level 2 microorganism and must be used within Biological Safety Level 2 facility or cabinet. Please consult your institution’s regulations regarding the use of this organism. For a detailed discussion on biological safety see the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), published by the CDC.
