靶标

  • 功能

    Ubiquitin-like protein that can be covalently attached to proteins as a monomer or a lysine-linked polymer. Covalent attachment via an isopeptide bond to its substrates requires prior activation by the E1 complex SAE1-SAE2 and linkage to the E2 enzyme UBE2I, and can be promoted by E3 ligases such as PIAS1-4, RANBP2 or CBX4. This post-translational modification on lysine residues of proteins plays a crucial role in a number of cellular processes such as nuclear transport, DNA replication and repair, mitosis and signal transduction. Involved for instance in targeting RANGAP1 to the nuclear pore complex protein RANBP2. Polymeric SUMO1 chains are also susceptible to polyubiquitination which functions as a signal for proteasomal degradation of modified proteins. May also regulate a network of genes involved in palate development.

  • 疾病相关

    Defects in SUMO1 are the cause of non-syndromic orofacial cleft type 10 (OFC10) [MIM:613705]; also called non-syndromic cleft lip with or without cleft palate 10. OFC10 is a birth defect consisting of cleft lips with or without cleft palate. Cleft lips are associated with cleft palate in two-third of cases. A cleft lip can occur on one or both sides and range in severity from a simple notch in the upper lip to a complete opening in the lip extending into the floor of the nostril and involving the upper gum. Note=A chromosomal aberation involving SUMO1 is the cause of OFC10. Translocation t(2;8)(q33.1;q24.3). The breakpoint occurred in the SUMO1 gene and resulted in haploinsufficiency confirmed by protein assays.

  • 序列相似性

    Belongs to the ubiquitin family. SUMO subfamily.
    Contains 1 ubiquitin-like domain.

  • 翻译后修饰

    Cleavage of precursor form by SENP1 or SENP2 is necessary for function.
    Polymeric SUMO1 chains undergo polyubiquitination by RNF4.

Question

Customer is not seeing a signal in WB with her most recent order for ab5316. The previous vial that she used worked very well and she did a side by side comparison. Order# 101464. Previous order 90661.

Answer

Thank you for your phone call and I'm sorry to hear that you are experiencing difficulty with ab5316. The replacement vials are being sent to your attention free of charge on order reference # 109485. The item is currently out of stock and so you should receive it early next week. You will receive emails regarding shipping to keep you updated. Please let me know how the replacement works out for you and if you have any additional questions.

Question

I tested the antibody first with my protein extract on SDS-PAGE. I found a very high non-specific background to the membrane. Subsequently, i did not apply any protein sample to my test membrane for troubleshooting. Therefore, i don't think it would be protein degradation or amount of protein or % of gel that caused the background problem since i have not used any of these in my testing. The image that i sent you was just empty clean membranes with no protein on it and as you can see, the antibody bound extremely well onto the membrane even i have use either 10% milk or 5% BSA to block it overnight before applying the antibody. Look forward to your suggestions Thanks

Answer

Thank you for getting back to me and for providing further information about your experiments. As we understand from your recent e-mail, after blocking the membrane (without running the samples) the primary antibody provided a very high background signal. Have you tested the secondary antibody alone (run a secondary control only) to see if this problem really comes from the primary or the secondary antibody? I have checked your order record and the delivery details in our system. Looking at FedEx website I can see that the package was held up at the customs for several days. It may well be that the antibody has just gone off during long delivery. We have the same batch in stock at the moment but I can send you a new vial from the same Lot (free of charge) if you wish to test it. Please get back to me and do let me know how to process. I am looking forward to hearing from you soon.

The lysate •How much protein was loaded: 50ug •What lysis buffer was used: Tris, SDS •What protease inhibitors were used: none •What loading buffer was used: Lammeli •Did you heat the samples: temperature and time: yes, boil for 3mins 4. Electrophoresis/Gel conditions/ Transfer conditions •Reducing or non reducing gel: reducing •Gel percentage : 8% •Transfer conditions: semi-dry 5. Blocking conditions •Buffer:TBS-T •Blocking agent: milk, BSA, serum, what percentage: Tried 5%, 10% milk, 5% BSA •Incubation time:for a few hours to overnight •Incubation temperature:25oC 6. Primary Antibody •Specification (in which species was it raised against): Rabbit •At what dilution(s) have you tested this antibody: 1:1000 as recommended •What dilution buffer was used:5%milk in TBS-T •Incubation time:1hr at 25oC or O/N at 4oC •Incubation temperature:4 and 25 oC tested •What washing steps were done:3x 10 mins with TBS-T 7.

Goat •At what dilution(s) have you tested this antibody:1/5000 •Incubation time 1hr at 4oC •Wash steps:3x10mins with TBS-T •Do you know whether the problems you are experiencing come from the secondary? It is working fine with my other westerns 8. Detection method ECl, ECl+, other detection method: ECL+ 9. Background bands •Have you eliminated the possibility that any background bands could be due to the secondary antibody? (Run a “No primary” control): other westerns work fine •Is the blocking step sufficient? yes (10% milk overnight) •Are your washing steps sufficiently stringent? (Multiple short washes are more effective than fewer longer wash steps) I have tried that too... •At what size are the bands migrating? Could they be degradation products of your target? empty membrane has high background too •Please provide an image of your blot (as an e-mail attachment, a faxed image is not sufficient) 10. Did you apply positive and negative controls along with the samples? Please specify. 11. Optimization attempts •How many times have you tried the Western? at least 5 times •Do you obtain the same results every time e.g. are background bands always in the same place? background everywhere even with empty membrane •What steps have you altered? empty (no protein) nitrocelluse and PVDF, respectively

Answer

Thank you for contacting us and for taking your time to fill in the Questionnaire and for providing more information about your Western blot assay. This antibody was raised against a recombinant full length protein from Arabidopsis thaliana and it has been characterized using samples from this species. Unfortunately, other species have not been tested yet and we do not know if ab5316 recognizes Sumo 1 in Aspergillus nidulans or not. Here we would like to make some suggestions which could improve the detection: As we understand from your e-mail, you do not use any proteinase inhibitors in the lysis buffer when preparing the samples. It is very important to apply a cocktail of different proteinases in order to prevent the degradation of the target. It is difficult to tell what may have happened in your samples without seeing the Wb image but it may well be that the high background due to protein degradation. You loaded 50 ug of protein onto the gel which is a bit too much. We usually advise 20-30 ug per lane, otherwise the gel is simply overloaded. The excepted band size is 12 kDa. In order to be able to detect a band at such a low MW level, you need to apply high percentage of gel i.e. 15%. If you use 8%, there is a very high chance that the separated target protein has run out of the gel. We hope that this information will be useful for you.
