Form 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.
Buffer If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
Reconstitution 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°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
and FAQs
Protein FAQs
Storage Condition Store at -20°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 Basically, we can dispatch the products out in 3-7 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.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Modulators of histone demethylase JMJD1C selectively target leukemic stem cells. Y Yang,FEBS OPEN BIO,2020

Applications: Surface Plasmon Resonance (SPR) analysis
Sample species: Human
Sample type: Cell
Review: SPR measurements of the binding between JDM-7 and JMJD1C/JMJD1B. The sensorgrams of JDM-7 binding to the chip-immobilized partial JMJD1C and or JMJD1B proteins are expressed in RU (response unit) versus the time after subtracting the control signal.

Target Data

Function Histone demethylase that specifically demethylates 'Lys-9' of histone H3, thereby playing a central role in histone code. Demethylation of Lys residue generates formaldehyde and succinate. May have tumor suppressor activity.
Gene References into Functions
  1. we found that KDM3B exhibits potential tumor-suppressive activity and transcriptionally modulates HOXA1 expression via RARE in AML. PMID: 28540746
  2. H3K9 demethylase KDM3B represses transcription of the angiogenesis regulatory gene, ANGPT1. PMID: 25413303
  3. High expression of KDM3B and KDM5A is associated with a better prognosis (no recurrence after mastectomy p=0.005 and response to docetaxel p=0.005)in breast cancer patients. PMID: 23266085
  4. evidence that the H3K9-me1/2 demethylase KDM3B might play a role in leukemogenesis via activation of lmo2 through interdependent actions with the histone acetyltransferase complex containing CBP PMID: 22615488
  5. A novel nuclear protein, 5qNCA is a candidate for the myeloid leukemia tumor suppressor gene on chromosome 5 band q31. PMID: 11687974
