Documentation

ATCC determines the biosafety level of a material based on our risk assessment as guided by the current edition of Biosafety in Microbiological and Biomedical Laboratories (BMBL), U.S. Department of Health and Human Services. It is your responsibility to understand the hazards associated with the material per your organization’s policies and procedures as well as any other applicable regulations as enforced by your local or national agencies.

ATCC highly recommends that appropriate personal protective equipment is always used when handling vials. For cultures that require storage in liquid nitrogen, it is important to note that some vials may leak when submersed in liquid nitrogen and will slowly fill with liquid nitrogen. Upon thawing, the conversion of the liquid nitrogen back to its gas phase may result in the vial exploding or blowing off its cap with dangerous force creating flying debris. Unless necessary, ATCC recommends that these cultures be stored in the vapor phase of liquid nitrogen rather than submersed in liquid nitrogen.

Comments
Cryptococcus neoformans Genome ORF Knockout Collection Version 1.0 (CnKOv1,0) The Madhani laboratory at the University of California-San Francisco recently generated deletions in approximately 1,200 Open Reading Frames (ORFs) (i.e., about 20% of the genome ORFs) of strain H99 (serotype A, var. grubii) of this organism. Each ORF deletion is made through homologous recombination in which a genome ORF is replaced by a PCR-generated DNA fragment containing selection marker natR and a unique barcode of 40 base pairs. The genotype of each of these gene knockout strains is MATalpha cnx####::natR, wherein x refers to an alphabet and #### to a 4-digit number and natR represents the gene that confers resistance to nourseothricin. For further information on the methodologies in making gene knockouts via homologous recombination and generation of 40-bp unique barcodes, see the publications: Davidson et al., Fungal Genetics & Biology 29: 38-48 (2000); and Nelson et al., Genetics 157: 935-947 (2001). Strains of Cryptococcus neoformans Genome ORF Knockout Collection (CnKOv1.0) are distributed as a set of fourteen 96-well standard microtiter plates (called CNKO-ps) or can be ordered individually.
