Protein Length
Full Length
Tag Info
N-terminal 6xHis-tagged
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.
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
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Description
The recombinant Human POLM protein is made through genetic engineering, also called gene splicing or recombinant DNA technology. By putting Human POLM genes into the genetic material of the E.coli system. These microorganisms can be used as factories or producers to make proteins for medical, academic and research uses. DNA to be manipulated it must be placed within a “transport vehicle” in which proteins may be produced from the genetic code of the DNA. The host cells used for Human POLM protein synthesis are E.coli cells, the whole production processes include isolation of POLM gene, amplification of POLM gene, cloning, POLM gene selection, and expression, and the POLM protein purification, the vector contains N-terminal 6xHis tag in addition to the specific DNA sequence, this facilitates the purification of the recombinant protein and it’s finally detected with a purity of 85%+ by SDS-PAGE.
POLM, also called Pol μ, is the only DNA polymerase with template-directed and terminal transferase activities. Pol μ is involved in the gap-filling repair synthesis during the non-homologous end joining (NHEJ) pathway for repair of the DNA double-strand breaks (DSBs). It contributes to the general error-prone bypass of certain kinds of DNA damages like 8-oxo-2′-deoxyguanosine (8-oxodG). Pol μ lacks proofreading activity, with an intrinsically high error rate of 10−3–10−5 for dNTP incorporation. Besides, Pol μ shows a strong preference for manganese over magnesium ions for its terminal deoxynucleotidyltransferase (TdT)-like activity.
