    IF using ab4447 to detect Ninein/NIN in MCF7 cells (human).

    The left hand panels are DAPI stained nuclei. The right hand panels are the same nuclei stained for Ninein/NIN.

    ab4447 was used at  1/1000.

    Ninein/NIN shows nuclear and centrosome staining, which is expected from the literature.

    ICC/IF image of ab4447 stained human HeLa cells. The cells were methanol fixed (5 min) and incubated with the antibody (ab4447, 1µg/ml) for 1h at room temperature. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Image-iTTM FX Signal Enhancer was used as the primary blocking agent, 5% BSA (in TBS-T) was used for all other blocking steps. DAPI was used to stain the cell nuclei (blue). Alexa Fluor® 594 WGA was used to label plasma membranes (red).

    ab4447 shows the characteristic nuclear and centrosome staining for Ninein/NIN.

Question

The customer would like to know the fixation protocol used by the researcher who provided the b&w image on the datasheet.

Answer

Thank you for your enquiry. The investigator who provided the images for our datasheet for ab4447 used this protocol: Fix in 3.5% paraformaldehyde (in PBS with final pH6.9). 10 minutes should be sufficient. Permeablize in 0.2% TX100 in KB buffer(150mM NaCl, 10mM TrispH7.8, 0.1%BSA) for 5 minute and wash in KB buffer (minus TX100) for another 5 minutes before primary antibody incubation, 1/1000. Please do not hesitate to contact us if you have additional questions.

Answer

Thank you for your enquiry. Further to our conversation this morning I have discovered that the immunogen used in this case was a fusion protein containing amino acids 32-506 of murine Ninein. I have retrieved the sequence from the EXPASY database for your convenience: ELTDLCHVLCLEDVGPVLQQTLLQDNLLGRVHFDQFKEALILILSRTLSSEEHFEES DCSPEAQPKYVRGGKRYGRRSLPEFQESGEEIEEVTVLEPLEEEARSSPIPAGDCGE HWKTQRSEEYEAEGQLRFWNPDDLNASHGGSCPPPDWIEEKLQEVCEDLGITRDGHL NRKKLVSICEQYGLQNVDGAMLEEVFLSLDPDGTMSVEDFFYGLFKTGKSLTPSAST PYRQLKRHLSMQSFDESGRRTATSSAMTSTIGFRVFSCLDDGMGQASVERILDTWQE EGIENSQEILKALDFSLDGNINLTELTLALENELLVTKNGIHQAALASFKAEIRHLL ERVDQVVREKEKLRSDLDKAEKLKSLMASEVDDHHAAIERRNEYNLRKLDEEYKERI AALKNELRQEREQMLQQVGKQRVELEQEIQKAKTEENYIRDRLALSLKENNRLETEL LENAEKLAEYESLTQKLQR I hope this information helps, please do not hesitate to contact me should you require further assistance.

Answer

Thank you for your enquiry and I'm sorry to hear that you are experiencing difficulty with ab4447. Without knowing more details regarding your protocol (dilutions tried? what was was your secondary antibody? what type of detection method are you using? what was the batch that you received? what type of cells are you using?), I would like to make a few suggestions. Try increasing the blocking incubation period. Also, the concentration of ab4447 may be too high; make sure to titrate the antibody. We do recommend using ab4447 at a concentration of 1:1000. Your secondary antibody may be binding non-specifically; make sure to a secondary control (no primary antibody), and also decrease the concentration of the secondary antibody. Please let me know if you have any additional questions.
