Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Tag Info
The following tags are available.
N-terminal His-tagged
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
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.
Buffer before Lyophilization
Tris/PBS-based buffer, 6% Trehalose, pH 8.0
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
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.
Lead Time
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.
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Cyclin-dependent kinase which displays CTD kinase activity and is required for RNA splicing. Has CTD kinase activity by hyperphosphorylating the C-terminal heptapeptide repeat domain (CTD) of the largest RNA polymerase II subunit RPB1, thereby acting as a key regulator of transcription elongation. Required for RNA splicing, probably by phosphorylating SRSF1/SF2. Required during hematopoiesis. In case of infection by HIV-1 virus, interacts with HIV-1 Tat protein acetylated at 'Lys-50' and 'Lys-51', thereby increasing HIV-1 mRNA splicing and promoting the production of the doubly spliced HIV-1 protein Nef.

  1. Heterozygous constitutional CDK13 mutations in 3 patients cause intellectual disability without cardiac defects. PMID: 29222009
  2. CDK13 RNA over-editing sites mediated by ADAR1 may serve as novel cancer driver events in HCC progression. PMID: 29996118
  3. heterozygous, likely dominant negative mutations affecting the protein kinase domain of the CDK13 gene result in a recognisable, syndromic form of intellectual disability, with or without congenital heart disease. PMID: 29021403
  4. Mutation in CHK13 gene is associated with congenital heart defects. PMID: 27479907
  5. Detailed phenotypic and molecular characterisation of 9 individuals with pathogenic variants in CDK13 is provided. Two individuals had novel CDK13 variants (p.Asn842Asp, p.Lys734Glu), while the remaining seven unrelated individuals had a recurrent, previously published p.Asn842Ser variant. PMID: 28807008
  6. CDK13 gene is amplified in different types of cancer indicate that this kinase can contribute to cancer development in human. PMID: 26886422
  7. CDK12 and CDK13 losses in HCT116 cells preferentially affect expression of DNA damage response. PMID: 25561469
  8. High CDK13 expression is associated with pancreatic cancer. PMID: 25216700
  9. Coincidently amplified CDK13, GMNN, and CENPF genes can play a role as common cancer-driver genes in human cancers. PMID: 22912832
  10. CDK13 interacts with cyclin K, and is required for self-renewal in ES cells. PMID: 22547058
  11. Data demonstrate that CDC2L5 is located in the nucleoplasm, where it directly interacts with the ASF/SF2-associated protein p32, a protein involved in splicing regulation. PMID: 16721827
