Handling procedures

Initial handling guidelines

Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.

1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.

Subculture guidelines
  • All seeding densities should be based on cell counts gained by established methods.
  • A guide seeding density of 2x104 cells/cm2 is recommended.
  • Cells should be passaged when they have achieved 80-90% confluence.

Notes

Although we aim to provide customers with a homozygous clone, feasibility will be dependent on the biology of the protein. Should only heterozygous edits be achieved, you will be notified of the outcome and be asked to confirm whether the cell line is acceptable. All clones will be accompanied with DNA sequencing data, and the mutation description.

Recommended control: Human wild-type HeLa cell line (ab255448). Please note a wild-type cell line is not automatically included with a knockout cell line order, if required please add recommended wild-type cell line at no additional cost using the code WILDTYPE-TMTK1.

• All seeding densities should be based on cell counts gained by established methods.

• A guide seeding density of 2x10E4 cells/cm2 is recommended.

• Cells should be passaged when they have achieved 80-90% confluence.

• Do not allow the cell density to exceed 7x10E4 cells/cm2.

We will provide viable cells that proliferate on revival.

Activity summary

NDUFB4 also known as NADH: ubiquinone oxidoreductase subunit B4 plays a role in the mitochondrial respiratory chain complex I. Weighing approximately 15 kDa NDUFB4 is expressed in mitochondria across various cell types. It couples electron transfer from NADH to ubiquinone thereby contributing to energy production process in cells. NDUFB4 is important in maintaining mitochondrial functionality due to its role in the electron transport chain.

Biological function summary

NADH: ubiquinone oxidoreductase subunit B4 is part of the NADH dehydrogenase complex I. This complex is involved in the initial step of the mitochondrial electron transport chain. NDUFB4 supports the bioenergetic functions of cells by facilitating redox reactions. It also helps establish the electrochemical gradient needed for ATP synthesis. This protein interacts synergistically with other subunits in complex I to ensure efficient energy conversion.

Pathways

NADH dehydrogenase complex I which includes NDUFB4 is central in oxidative phosphorylation. This process supports energy production by converting NADH and FADH2 into ATP. NDUFB4 is integrally linked with proteins like NDUFS2 and NDUFV1 within this pathway ensuring electron transport is seamless. Complex I contributes to metabolic processes like the TCA cycle by feeding the mitochondria with necessary energy intermediates.

Associated diseases and disorders

Malfunction of NDUFB4 in complex I links to mitochondrial diseases such as Leigh syndrome. This syndrome affects central nervous system development. Mitochondrial encephalopathies are another group where NDUFB4 involvement is observed. In these conditions proteins like NDUFA1 and mitochondrial DNA mutations can manifest similar neurodegenerative symptoms due to impaired oxidative phosphorylation. Therefore understanding NDUFB4’s function helps in identifying therapeutic interventions for these disorders.
