Product details

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.

We will provide viable cells that proliferate on revival.

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.
  • Do not allow the cell density to exceed 7x104 cells/cm2.
Culture medium

F-12K + 10% FBS

Cryopreservation medium

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

Leptin also known as the OB protein is a hormone with a molecular weight of approximately 16 kDa. Primarily it is produced by adipocytes in white adipose tissue and to a lesser extent in the placenta stomach and other tissues. This protein plays a significant role in energy homeostasis by conveying information to the central nervous system regarding fat storage. In scientific studies leptin is often measured using methods like the leptin ELISA kit or mouse leptin assay to monitor its levels and function.
Biological function summary

Leptin regulates food intake and energy expenditure by binding to its receptors in the hypothalamus. It is an important part of the feedback loop to manage body weight and appetite. Leptin is not part of a larger protein complex and acts directly on its target tissues. By signal transduction pathways it influences cellular processes such as metabolism and even impacts fertility and immune responses.

Pathways

Leptin is involved in the neuroendocrine signaling pathway and the MAPK/ERK pathway. In the neuroendocrine system leptin interacts with proteins like proopiomelanocortin (POMC) and neuropeptide Y (NPY) to manage appetite and energy use. Additionally it activates the JAK/STAT pathway when binding to its receptor which influences gene expression involved in metabolism and inflammation.

Leptin is linked to obesity and type 2 diabetes. Leptin deficiencies or resistance can lead to metabolic disorders as the hormone's signaling is disrupted affecting energy balance and storage. Its connection to adiponectin another hormone derived from fat tissue is critical in understanding these conditions; while leptin promotes inflammation adiponectin has anti-inflammatory effects. Exploring these proteins' roles and their balance offers insights into treatments for obesity-related disorders.
