  • Function

    ICAM proteins are ligands for the leukocyte adhesion protein LFA-1 (integrin alpha-L/beta-2). During leukocyte trans-endothelial migration, ICAM1 engagement promotes the assembly of endothelial apical cups through ARHGEF26/SGEF and RHOG activation. In case of rhinovirus infection acts as a cellular receptor for the virus.
  • Sequence similarities

    Belongs to the immunoglobulin superfamily. ICAM family.
    Contains 5 Ig-like C2-type (immunoglobulin-like) domains.
  • Post-translational

    Monoubiquitinated, which is promoted by MARCH9 and leads to endocytosis.
  • Cellular localization

I sorry to hear about the volume of the antibody; we always fill vials 4-5ul extra so quick spin is required to extract the whole volume. I am sure you have given a quick spin to vial before opening it, if it hasn't been done then it will worth to try.

On the other hand I have let our logistic team know about this issue and I can reassure you that they have taken the necessary actions.

Thank you for your enquiry.

As the Swiss-Prot database highlights, the mature ICAM1 protein is heavily N-Glycosylated. There at least 9 potential site for this type of post-translational modification which can significantly alter the band size. I would advise you to consult these sites for further information:

If you need any further assistance in the future, please do not hesitate to contact me.

Thank you very much,

We used ICAM-1 (Ab, ab2213), but this antibody gives many unspecific bands. I tried it in many different conditions, however, it still gives me the same results.

· Lysis buffer - would be very important to know

We are using special a kit from abcam ab65400 (Plasma membrane protein extraction kit) in which lysis buffer is included.

· Amount of protein loaded - (protein endogenously expressed or transfected cells)

20-30 μg protein per lane.

· Electrophoresis and transfer conditions

The samples were run at 100 and 150 V, one dimensional SDS-PAGE gel was used. For transfering, Protein transfer verifiedusing Ponceau red.

· Blocking conditions

We used 5% and 3% fat free dry milk and also we tried 5% and 3% BSA. Blocking time, once 1 hour and in other run was 30 minutes at 25˚C

· Primary antibody conditions (diluent/dilution, incubation time/temperature)

Concentration or dilution

1/1000 to 1/250 under reducing and non-reducing condition.

· Diluent buffer

1X PBS+0.1% Tween in 5% BSA.

· Incubation time

Once over night at 4C and another 1 hour and 30 minutes at room temperature.

· Secondary antibody conditions (diluent/dilution, incubation time/temperature)

Secondary antibody species gout which reacts against mouse antibodies, the dilution is from 1/10000 to 1/20000 in 1X PBS+0.1% Tween in 5% BSA for one hour at 25˚C.

Wash steps and washing buffer: 1X PBS+0.1% Tween 3 times each one 10 minutes.

· Detection method:

ECL (super signal west pico chemiluminescent)

· Positive control
I used Calnexin, and Na/K ATPase (ab7671) as membrane markerThank you for your understanding and co-operation in this matter. I look forward to hearing from you soon and resolving this issue as soon as possible.

Thank you for your response.

Could you please specify the size of the non-specific bands? Are they lower or higher than the expected size (58 kDa)? Could you attach an image (saved as a jpeg file) to your e-mail so that I can have a look at the bands.

I look forward to hearing from you soon.

Thank you for your enquiry.

I can confirm that ab18414 can be stored at 4oC as described on the datasheet. This should not be aliquotted and frozen.

The others I would recommend to aliquot and freeze immediately. Keeping them at 4oC for a few weeks should not significantly affect the staining. However, we would recommend to follow the individual storage instructions provided on the individual datasheets as soon as possible after delivery. This will help to ensure that the antibody remains stable and that we can continue to provide our guarantee.

I hope this will be helpful to you. If you have any further questions, please do not hesitate to contact us.

Thank you for calling us yesterday and for alerting us to the problem you are experiencing with our product. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

As we discussed on the phone, I have attached our questionnaire so that we can gather further information regarding the samples tested and the protocol used. Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we can make that may improve the results.

This information will also allow us to investigate this case internally and initiate additional testing where necessary.

I look forward to receiving your reply.
