  • 蛋白标签：
    N-terminal 10xHis-tagged
  • 产品提供形式：
    Liquid or Lyophilized powder
    Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
  • 缓冲液：
    Lyophilized from Tris/PBS-based buffer, 6% Trehalose, pH 8.0
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
  • 保质期：
    The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
    Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
  • 货期：
    Basically, we can dispatch the products out in 1-3 working days after receiving your orders. Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
    Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
  • 注意事项：
    Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
  • Datasheet & COA：

    1. Ten new silent KEL alleles were identified in Japanese individuals with the Ko phenotype. PMID: 29280152
    2. description of four new KEL*01M alleles PMID: 26996808
    3. The expression of Kell glycoprotein on RBCs is not critical to the erythrocyte function PMID: 26308465
    4. Through molecular genotyping we also identified polymorphisms in RhCE, Kell, Duffy, Colton, Lutheran and Scianna loci in donors and patients. PMID: 25582271
    5. A relatively increased KEL1 antigen expression in KEL:1,2null and KEL:1,2mod individuals suggest that the expression of Kell-XK complexes depends on the availability of the XK protein. PMID: 25156717
    6. High-throughput Kell, Kidd, and Duffy matrix-assisted laser desorption/ionization, time-of-flight mass spectrometry-based blood group genotyping of 4000 donors shows close to full concordance with serotyping and detects new alleles. PMID: 24845979
    7. After sequencing the whole KEL gene, we found three new missense mutations: c.455A>G (p.Tyr152Cys) at Exon 5, c.2111A>C (p.Pro704His) at Exon 19, and c.1726G>C (p.Gly576Arg) at Exon 16. PMID: 25041236
    8. A new allele, KEL(Thr193Met, Pro326Leu), has a drastic effect on the Kell glycoprotein probably due to defects in protein trafficking or reduced membrane integration. PMID: 24588083
    9. Sequence analysis of genomic DNA from 2 Caucasian Brazilian women revealed a new homozygous change in KEL Exon 2, a guanine to an adenine substitution at Position 71 (c.71G>A, NCBI_ss#: 831878329) leading to a premature stop codon. PMID: 24506314
    10. A compensatory mechanism of the KELmod allele deficient expression in heterozygote patients may exist. Retrospective analysis of 80,000 subjects showed a local KEL:1,-2 frequency 4 times lower than expected. PMID: 23727116
    11. A rare allele in this family has been numbered KEL*02M.04 and contains a Gly703Arg substitution that appears to cause weakened expression of Kell antigens and a Kmod phenotype when in trans with a null allele in the propositus. PMID: 24795954
    12. Systematic DNA analysis showed that the number of discordant phenotype/genotype results, related to silent KEL*02 alleles was higher than expected in France. PMID: 23581578
    13. These findings identify the translational start site and define the full cytoplasmic tail of the human Kell glycoprotein. PMID: 23721226
    14. Novel IVS6-13C>T mutation recognized as a cause of discrepancy between phenotyping and genotyping in KEL*3,4 polymorphism identification. PMID: 20609202
    15. x-ray analysis of Kell blood group protein PMID: 12842980
    16. Kell K2 antigen is a catalytically active metalloprotease, but the rare Kell K1 antigen is inactive PMID: 15769748
    17. KEL6 red blood cells have endothelin-3-converting enzyme activity PMID: 16423827
    18. Results demonstrate the lack of Kell expression in rodent neuronal cells and strongly suggest the same for human cerebral tissue, in which the Kellprotein was exclusively observed on RBCs in cerebral blood vessels. PMID: 17379193
    19. This is the first description of the KEL*1,3 allele encoding KEL1 and KEL3 on the same molecule. PMID: 19347978
    20. In screening 87665 unrelated healthy blood donors in China, two K(0) probands were detected; in exon 3, 185insT (Ser62Phe and a premature stop codon in exon 4 PMID: 19747286
