Cellosaurus K562/GM-CSF (CVCL_A8HT)

[Text version]
Cell line name K562/GM-CSF
Synonyms K562 GM-CSF; K562GM-CSF; GM-K562
Accession CVCL_A8HT
Resource Identification Initiative To cite this cell line use: K562/GM-CSF (RRID:CVCL_A8HT)
Comments Population: Caucasian.
Biotechnology: Used for the production of the Sorento Therapeutics STI-6991 SARS-CoV-2 (COVID-19) vaccine candidate. The cell line which is lethally irradiated is used to produce the recombinant SARS-CoV-2 spike protein rSARS-CoV-2 which is the active part of the vaccine formulation (PubMed=32289117).
Characteristics: Does not express HLA class I or II antigens, potentially decreasing the magnitude of the alloresponses generated on repeated immunizations (PubMed=10466632).
Transfected with: HGNC; 2434; CSF2.
Transfected with: UniProtKB; P00557; Escherichia coli hygromycin-B 4-O-kinase (hph) (HygR).
Derived from site: In situ; Pleural effusion; UBERON=UBERON_0000175.
Sequence variations
  • Gene fusion; HGNC; 76; ABL1 + HGNC; 1014; BCR; Name(s)=BCR-ABL1, BCR-ABL (from parent cell line).
  • Mutation; HGNC; 11998; TP53; Simple; p.Gln136fs*13 (c.406_407insC); Zygosity=Homozygous (from parent cell line).
Disease Blast phase chronic myelogenous leukemia, BCR-ABL1 positive (NCIt: C9110)
