Western blot - Human NF1 knockout MCF7 cell line (AB286416)

Anti-NF1 antibody [EPR22989-68] (ab238142) staining at 1/1000 dilution, shown in green; Mouse anti-CANX [CANX/1543] (ab238078) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab238142 was shown to bind specifically to NF1. A band was observed at 180-270 kDa in wild-type MCF7 cell lysates with no signal observed at this size in NF1 knockout cell line. To generate this image, wild-type and NF1 knockout MCF7 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Rabbit IgG H&L 800CW and Goat anti-Mouse IgG H&L 680RD at 1/20000 dilution.

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.

Recommended control: Human wild-type MCF7 cell line (ab288560). 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.

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
  • Slow to trypsinise.
  • All seeding densities should be based on cell counts gained by established methods.
  • A guide seeding density of 5-7x104 cells/cm2 is recommended.
  • Cells should be passaged when they have achieved 80-90% confluence.
Culture medium

MEM + 10% FBS + 0.01 mg/ml bovine insulin

Cryopreservation medium

Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.

Supplementary information

Neurofibromin is a protein that functions as a Ras GTPase-activating protein acting to promote the hydrolysis of Ras-bound GTP to GDP which inactivates Ras signaling. This regulatory function involves the suppression of excessive cell proliferation and differentiation. Alternate names for neurofibromin include NF1 or neurofibromin 1. The mass of neurofibromin is approximately 327 kDa. Neurofibromin is expressed widely across various tissues with notable expression in the nervous system and the brain.
Biological function summary

Neurofibromin regulates pathways involved in cell growth and development. It does not form part of a large multiprotein complex but interacts with microtubules and other signaling proteins to carry out its regulatory functions. Neurofibromin primarily affects pathways that manage cell cycle progression and it plays a critical role in inhibiting uncontrolled cell growth ensuring proper cellular homeostasis.

Pathways

Neurofibromin fits into the Ras-MAPK pathway where it controls the activity of Ras an important regulatory protein involved in signal transduction related to cell division and differentiation. Neurofibromin's action on Ras directly impacts the activation of the MAPK pathway which is important in mediating cellular responses to growth signals. This protein also interacts functionally with proteins like SOS1 another regulator of Ras emphasizing its role in fine-tuning signal cascades that ensure balanced cellular function.

Neurofibromin's dysregulation is most commonly associated with neurofibromatosis type 1 a genetic disorder characterized by the development of benign tumors in the nervous system. The loss of neurofibromin function leads to unregulated Ras activity resulting in tumorigenesis. Additionally neurofibromin is implicated in certain sporadic cancers due to its role in controlling cell proliferation. In neurofibromatosis type 1 interactions between neurofibromin and proteins such as p53 a known tumor suppressor highlight its significance in disease pathways and tumor suppression mechanisms.
