Western blot - Human MSH3 knockout A549 cell line (AB288875)

False colour image of Western blot : Anti-MSH3 antibody [RM405] staining at 1/1000 dilution, shown in green; Mouse anti-GAPDH antibody [6C5] (ab8245) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab275928 was shown to bind specifically to MSH3. A band was observed at 140 kDa in wild-type A549 cell lysates with no signal observed at this size in MSH3 knockout cell line ab288875. To generate this image, wild-type and MSH3 knockout A549 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 5 % 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 A549 cell line (ab288558). 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
  • 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.

Supplementary information

The mutS homolog 3 (MSH3) protein plays an important role in DNA mismatch repair. It is part of the family of MutS proteins and is sometimes referred to by its gene name MSH3. MSH3 forms a heterodimer with MSH2 to create MutSβ. This complex targets insertion and deletion loops. The mass of MSH3 is approximately 127 kDa. Expression of MSH3 occurs in various tissues with high levels in the colon small intestine and testis.
Biological function summary

MSH3 contributes to genome stability by correcting DNA replication errors. As part of the MutSβ complex it identifies and initiates repair of insertion and deletion loops which helps maintain genomic integrity. In eukaryotes MSH3 along with its partner MSH2 cooperates with other proteins such as MLH1 and PMS2 to ensure proper mismatch repair. These interactions help to prevent mutations from becoming permanent.

Pathways

MSH3 participates in the DNA mismatch repair pathway important for maintaining genomic fidelity. It works closely with MSH2 to form MutSβ enhancing the repair of small loops. Another important association includes the MLH1-PMS2 complex within the mismatch repair pathways. This collaboration ensures errors in DNA during replication do not lead to genomic instability.

Mutations or malfunctioning of MSH3 have been associated with colorectal cancer and Lynch syndrome. Alterations in MSH3 can impair DNA repair processes contributing to cancer development. The MSH2 protein which pairs with MSH3 also plays a critical role in these disorders. Understanding MSH3 function helps illuminate its involvement in genetic stability and its impact on health.
