Properties

Applications

Our Abpromise guarantee covers the use of ab60 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

ChIP Use at an assay dependent dilution.

Target

  • Function
    Component of the origin recognition complex (ORC) that binds origins of replication. DNA-binding is ATP-dependent, however specific DNA sequences that define origins of replication have not been identified so far. ORC is required to assemble the pre-replication complex necessary to initiate DNA replication.
  • Sequence similarities
    Belongs to the ORC1 family.
    Contains 1 BAH domain.
  • Developmental stage
    Expression is cell-cycle regulated, it starts to accumulate in mid-G1 phase, reaches a peak at the G1/S boundary, and decreases to a basal level in S phase (at protein level).
  • Cellular localization
    Nucleus.

    Thanks for your mail. I have some more questions. I read the reviews and reviews are not good regarding the antibody. I dont understand if the immunogen is a full length human Orc protien which has a mol weight of 97 Kda, why you get a band in pl...

    Thank you for your patience, I was away on vacation and was thus unable to reply to you sooner. The immunogen used was Human ORC1 protein. The report of ab60 detecting a 120 kDa band was reported by a customer who used the antibody (see review on the o...

    Customer would like to know: Datasheet says that by Western blot, this antibody detects a band of 120 kDa, which corresponds to the predicted molecular weight of ORC 1. But customer says that human ORC1 is approx 97-100 kDa. Can this be clarified?

    Thank you for your enquiry. ORC1 from the yeast S. cerevisiae is 120 kDa, and human ORC1 is 97 kDa so the expected band size indicated on the datasheet is referring to yeast. However, a customer's review (please see the review tab on the online datashe...

    I would like to know the conditions at which this Ab can be detected in normal western blotting analysis (i.e. pH, PBS/ TBS/ tween) thank you

    The antibody should work using normal Western blotting conditions (see general protocol on our website for more information), but it seems that the ORC1 protein is quite unstable (see review on this antibody on the antibody datasheet, top right hand co...

    We already bought 3 vials of the anti-orc1 antibody but none of them is working. Probably the western blotting conditions we are using are not right, so could you please tell us the proper conditions?

    Is your ORC1 antibody recognize S.cerevisiae Orc1?

    We have no reports of it being tested on S.cerevisae Orc1. If it is closely homologous to mammalian then it may well do.

    Does this antibody react with mouse ORC1 on western blots. If it does I would like to buy it.

    Yes, it does react with mouse ORC1
