Passage of GIAB samples

[NahyunKong]

Hi,

I'm currently working with fastq files of the HG002 and HG005 cell lines, sequenced using the Illumina 300x platform. These files were downloaded from the following links:
I am using fastq files downloaded from here:

• HG002: https://ftp-trace.ncbi.nlm.nih.gov/ReferenceSamples/giab/data_indexes/AshkenazimTrio/sequence.index.AJtrio_Illumina300X_wgs_07292015_updated.HG002
• HG005: https://ftp.ncbi.nlm.nih.gov/ReferenceSamples/giab/data_indexes/ChineseTrio/sequence.index.ChineseTrio_Illumina_6kb_matepair_wgs_09232015_updated.HG005

I wonder what is the passage of these cell lines. My research involves analyzing mitochondrial variants in these samples. It's crucial to know whether these samples are from early or late passages. If there's any resource or information available regarding the passage number of these cell lines, would you please share it?

Thank you!
