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. 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.
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
3-7 business days
Notes
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Background

Function
Single-stranded DNA-binding protein that participates in viral DNA replication, recombination, and repair (Probable). Coats the lagging-strand ssDNA as the replication fork advances. Stimulates the activities of viral DNA polymerase and DnaB-like SF4 replicative helicase, probably via its interaction with the helicase assembly factor. Together with DnaB-like SF4 replicative helicase and the helicase assembly factor, promotes pairing of two homologous DNA molecules containing complementary single-stranded regions and mediates homologous DNA strand exchange. Promotes also the formation of joint molecules. mRNA specific autogenous translational repressor.
Gene References into Functions
  1. the C-domain of bacteriophage T4 gene 32 protein has a role in ssDNA binding and dsDNA helix-destabilization PMID: 29634784
  2. Characterization of structural and thermodynamic aspects of gp32 binding cooperativity that are central to the function of this single stranded DNA binding protein with the T4 DNA replication. PMID: 26275774
  3. The results show that single gp32 molecules interact most directly and specifically near the 3'-end of these ssDNA oligomers, thus defining the polarity of gp32 binding with respect to the ssDNA lattice, and that only 2-3 nts are directly involved in this tight binding interaction. PMID: 26275775
  4. Gp59-DNA interactions are needed to load Gp41 onto nascent or collapsed replication forks lacking clusters of Gp32 and to coordinate bidirectional replication from T4 origins. PMID: 24338568
  5. UvsW-catalyzed unwinding of recombination intermediates such as D-loops and static X-DNA (Holliday junction mimic) to ssDNA products is enhanced by the gp32 protein. PMID: 23732982
  6. binding of T4 gene 32 protein to single- and double-stranded DNA is electrostatically regulated PMID: 15994897
