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.

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 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.

Target Data

Function Heterodimeric electron transfer flavoprotein that accepts electrons from several mitochondrial dehydrogenases, including acyl-CoA dehydrogenases, glutaryl-CoA and sarcosine dehydrogenase
Gene References into Functions
  1. Data suggest that ETF (heterodimer of ETFA and ETFB) catalyzes irreversible and pH-dependent oxidation of 8alpha-methyl group of FAD to form to 8-formyl-FAD (8f-FAD). PMID: 29301933
  2. our results indicate that genetic variants in ETFA may modify individual susceptibility to non-GBM of glioma in the Han Chinese population and support the role of the ETFA genes in the occurrence of glioma. PMID: 28320150
  3. the mechanism of tert-butyl hydroperoxide-induced an apoptosis cascade and endoplasmic reticulum stress in hepatocyte cells by up-regulation of ETFA, providing a new mechanism for liver injury. PMID: 24394546
  4. These results are consistent with the electron transfer flavoprotein alpha II domain adopting orientations in solution that deviate from the crystal structure of free ETF towards the active, substrate-bound orientation. PMID: 21308847
  5. investigations are compatible with the notion that the ETFalpha-T171 variant displays an altered conformational landscape that results in reduced protein function under thermal stress PMID: 21219902
  6. Data established structural hotspots within the ETF fold, and provided a rationale for the prediction of effects of mutations in ETF. PMID: 20674745
  7. These studies indicate that a series of conformational changes occur during the assembly of the TMADH.ETF electron transfer complex and that the kinetics of assembly observed with mutant TMADH or ETF complexes are much slower PMID: 11756429
  8. Tissue samples from 16 unrelated patients with ETF deficiency were analysed and the majority of the patients had mutations in the ETFA gene. PMID: 16510302
  9. No mutations in electron-transfer-flavoprotein but maternal riboflavin deficiency led to multiple acyl-CoA dehydrogenation deficiency PMID: 17689999
