靶标

  • 功能

    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.

  • 疾病相关

    Defects in ORC4 are the cause of Meier-Gorlin syndrome type 2 (MGORS2) [MIM:613800]. MGORS2 is a syndrome characterized by bilateral microtia, aplasia/hypoplasia of the patellae, and severe intrauterine and postnatal growth retardation with short stature and poor weight gain. Additional clinical findings include anomalies of cranial sutures, microcephaly, apparently low-set and simple ears, microstomia, full lips, highly arched or cleft palate, micrognathia, genitourinary tract anomalies, and various skeletal anomalies. While almost all cases have primordial dwarfism with substantial prenatal and postnatal growth retardation, not all cases have microcephaly, and microtia and absent/hypoplastic patella are absent in some. Despite the presence of microcephaly, intellect is usually normal.

Answer

Thank you for your enquiry. I am sorry to hear that you have been having difficulties with this antibody. This antibody was assigned "ChIP grade" status following its application in the following publication; Todorovic V et al. Human origins of DNA replication selected from a library of nascent DNA. Mol Cell 19:567-75 (2005). PubMed: 16109380 I have examined the protocol that they employed and the protocol that you are using is indeed very similar. As a control I would like to ask whether you have been incorporating a control antibody such as anti-histone H3. Also can you tell me the positive control loci that you have been using? Do you have a locus that you are expecting ORC4L to be recruited to? Is ORC4L constantly associated with this locus, or recruited in a stepwise process? I look forward to hearing from you.

BATCH NUMBER 44011 ORDER NUMBER A39762 DESCRIPTION OF THE PROBLEM No signal when using Anti-ORC4L, not even for the positive control. However I can detect ORC2. SAMPLE HeLa nuclear extract PRIMARY ANTIBODY Anti-ORC4L, abcam, 1:500 dilution, 90' incubation, wash once with TS buffer (10 mM Tris pH 8.0, 200 mM NaCl) wash twice with TS-NP40 (0.05% NP40), wash once with TS SECONDARY ANTIBODY Anti-goat, IgG-HRP, Santa Cruz, 1:2000, 90' incubtaion at RT, wash as the primary antibody. DETECTION METHOD ECLPlus POSITIVE AND NEGATIVE CONTROLS USED Use HeLa nuclear extract as positive control (which give strong signal with Anti-ORC2 Ab). ANTIBODY STORAGE CONDITIONS -20 C SAMPLE PREPARATION Protease inhibitors from Sigma. Mix sample with 2x SDS Loading buffer, heat for 5'. ELECTROPHORESIS/GEL CONDITIONS Reducing, 8-16% TRANSFER AND BLOCKING CONDITIONS Transfer O/N, 0.120 A HOW MANY TIMES HAVE YOU TRIED THE APPLICATION? 3 HAVE YOU RUN A "NO PRIMARY" CONTROL? No DO YOU OBTAIN THE SAME RESULTS EVERY TIME? Yes WHAT STEPS HAVE YOU ALTERED? Used Anti-ORC4 at 1:250 dilution, avoid Sodium azide, incubate primary over night at 4 C, incubate secondary over night at 4 C, new ECLPlus kit.

Answer

Thank you for your e-mail. I'm really sorry to hear you are having problems with this antibody and would like to give you a few suggestions. You have not mentioned the amount of protein loaded onto the gel. If it is under 30-40ug this may be too low and hence there is very little ORC4L protein to be detected. You may also have a very low concentration of ORC4L in your samples and a western blot detection may not be enough to detect the protein. I would recommend trying a cell line which is known to express ORC4L at detectable levels, such as Jurkat and NSO (mouse) cell lysates (we have Jurkat cell lysat in our catalogue:ab7899). Can I confirm also that you add Tween 20 in the buffer in which the primary antibody is diluted in, as it helps the penetration of the antibody into the membrane? Do you block the membrane with milk or BSA? Finally, our datasheet recommends trying 1-3ug/ml so I would suggest you try 3ug/ml and maybe 5ug/ml too? This may help detecting any low amounts of protein you may have in your samples. I hope this information helps, but please do not hesitate to contact me if you need further advice, Good luck with your westerns!
