Application Abreviews Notes
WB 1/100 - 1/500. Detects a band of approximately 22 kDa (predicted molecular weight: 22 kDa).
ELISA 1/1000.
ICC/IF Use a concentration of 1 - 5 µg/ml.
IHC-P 1/50 - 1/100. Perform heat mediated antigen retrieval via the microwave method before commencing with IHC staining protocol.


  • Function
    Apoptosis-inducing protein that, which can overcome BCL2 suppression. May play a role in repartitioning calcium between the two major intracellular calcium stores in association with BCL2.
  • Sequence similarities
    Belongs to the NIP3 family.
  • Cellular localization
    Mitochondrion. Mitochondrion membrane. Coexpression with the EIB 19-kDa protein results in a shift in NIP3 localization pattern to the nuclear envelope. Colocalizes with ACAA2 in the mitochondria.

  • This image shows human colon carcinoma stained with ab38621 at 5ug/200ul dilution.
  • ICC/IF image of ab38621 stained HeLa cells. The cells were 4% PFA fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab38621, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

Thank you for taking the time to complete our questionnaire and contact us. I am sorry to hear you have had difficulty obtaining satisfactory results from our products.

Reviewing this case, I would like to offer some suggestions to help optimise the results from ab8399.

-I would recommend the use of a positive control, as it is a good indicator of the antibody performance. Mouse brain tissue or Ramos cell lysate are recommended.

-BNIP3L is a phosphorilated protein. Milk is not recommended as a blocking agent when phospho-proteins, as the casein could break the phosphorilated positions. Instead, I would recommend using 5% BSA for 1 hour at RT, which in addition is a milder blocking agent and can help visualize the bands of interest.

- Increase the protein rate in your samples, using a mitochondrial lysate instead of a total cell lysate. RIPA buffer could be a good choice to do it.

-Increase the antibody concentration. Try 1/50 or 1/100 in an attempt to improve the results.

-For the washing process I would recommend using TBST, and perform 4 washes of 10 minutes each.

I hope this suggestions help improve the results from the antibody. Please do not hesitate to contact us for further assistance.
