Background FLOT2 (Flotillin 2), also known as ESA1 or M17S1, is a protein that in humans is encoded by the FLOT2 gene. Schroeder et al. (1991) isolated a cDNA for an epidermal surface antigen believed to be involved in epidermal cell adhesion. By analysis of a somatic cell hybrid panel and in situ hybridization using the ESA cDNA, the gene was mapped to 17q11-q12 in the region containing the NF1 gene. Bickel et al. (1997) found that mouse Flot2 consistently copurifies with Flot1 and with caveolin-1 in the purification of caveolin-rich membranes. Using a quantitative proteomic analysis of cultured mouse neuronal stem cells, Li et al. (2012) found that palmitoylation and oligomerization of flotillin-2 was abolished in homozygous Dhhc5 mutant neuronal stem cells. The absolute amount of flotillin-2 was not changed in Dhhc5 mutant neurons.

Customer Q&As

  • Q: Do you offer BSA-free antibodies? Keyword: Bovine serum albumin, carrier protein, conjugation
    A: Yes, please contact us at [email protected] for more information about BSA-free antibodies and availability. The new BSA-free formula uses trehalose as a replacement to BSA. We have tested many alternative chemicals and found that trehalose protects the antibodies the best.
  • Q: Can I conjugate markers to this antibody? Can I link custom conjugates to this antibody? Keyword: conjugation
    A: The antibody is stored with BSA and cannot be conjugated with markers. Carrier free antibodies are available upon request. Please contact [email protected]
  • Q: What should I use for negative control?
    A: Please contact us for negative control suggestions. You can also check expression databases such as genecards, uniprot etc. Due to logistic reasons, we do not sell serum or lysates that we use internally for positive or negative control.
  • Q: Where can I find troubleshooting information? What should I do if I have unexpected bands, high background, no signal, weak signal
    A: You can find Boster's troubleshoot guides under tech support tab. Please contact us for further assistance on troubleshooting your experiment.
  • Q: What is the immunogen sequence of this antibody? Is this antibody polyclonal or monoclonal?
    A: You can find the immunogen sequence under "
  • Q: What is the expected band size? Why is it different than the observed band size?
    A: The expected band size is predicted on the size of the protein. The actual band size may be affected by a few other factors including but not limited to:<br>1. Post-translational modification:phosphorylation, methylation, glycosylation etc. These modifications prevent SDS molecules from binding to the target protein and thus make the band size appear larger than expected<br>2. Post-translational cleavage: this can cause smaller bands and or multiple bands <br><br>3. Alternative splicing: the same gene can have alternative splicing patterns generating different size proteins, all with reactivities to the antibody. <br><br>4. Amino Acid R chain charge: SDS binds to positive charges. The different size and charge of the Amino Acid side chains can affect the amount of SDS binding and thus affect the observed band size.<br>5. Multimers: Multimers are usually broken up in reducing conditions. However if the interactions between the multimers are strong, the band may appear higher., <br>
  • Q: What is the suggested dilution ratio for Western Blot (WB), Immunohistochemistry (IHC) and or ELISA standards? What is the optimal pH for the sample?
    A: Check the datasheet for the product for details on dilution ratios for different experiments. You can find the datasheet button on the right side of the product page.
  • Q: What is the protocol you used for your Western blotting (WB) and Immunohistochemistry (IHC)?
    A: Check our protocols under the tech support tab.
