一般描述

Proteoprep 20是一种免疫去除试剂盒，可从血浆或血清中去除20种高丰度干扰蛋白，从而分析低丰度蛋白。Proteoprep 20 可去除的蛋白：白蛋白、IgG、转铁蛋白、纤维蛋白原、gA, α2巨球蛋白、IgM, α1抗胰蛋白脢、补体蛋白C3、 触珠蛋白、载脂蛋白A1、载脂蛋白A3和载脂蛋白B；α1酸性糖蛋白、铜蓝蛋白、补体蛋白C4、补体蛋白C1q、IgD、前白蛋白和纤维蛋白溶酶原。

应用

ProteoPrep 20血浆免疫去除试剂盒可从为进一步的蛋白质组分析而制备的人血浆或血清样本中特异性去除20种最高丰度的蛋白质。无论您采用二维还是三维电泳，一维还是多维色谱，亦或是直接进行质谱，这种去除方法均可实现更深的血浆蛋白质组渗透率。这一方法基于小分子量重组免疫亲和配体与可在支撑物上进行高密度偶联的传统抗体的独特偶联过程。可选的配体确保了最佳的特异性。对于人血浆或血清，其典型的总蛋白去除率为97-98%（质量）。

特点和优势

• 提高可视化低丰度蛋白和生物标志物的能力 – 可有效去除>99% 的二十种最高丰度蛋白质，可将特定蛋白载量提高50倍，从而增加了低丰度蛋白可视化的几率

• 独特的抗体亲和介质 – 新型高密度抗体亲和介质显示出了更高的特异性，可以减少污染，去除污染物能力相对于所有现有产品大幅提升

• 方便的离心柱形式 – 快速去除污染物和回收，提高了通量和验证能力，成为了所有蛋白质组实验室的首选

  1. Can the Product PROT20, ProteoPrep Plasma Immunodepletion Kit, columns be re-used?

    With proper cleaning and storage, each column may be reused at least 100 times.

  2. The Product PROT20, ProteoPrep Plasma Immunodepletion Kit, bulletin indicates that 8 microliters of plasma are loaded on to the column. I have more than 8 microliters of plasma. Can I load greater than 8 microliters according to the procedure? 

    We optimized the protocol for dilution of about 8 microliters of plasma to 100 microliters with the 1× Equilibration Buffer. It is probably best to dilute 8 or so microliters at a time and load on the column for depletion. This process can be repeated for the full sample.

  3. Can I use Product PROT20, ProteoPrep Plasma Immunodepletion Kit, columns on plasma from other species, e.g. monkey?

    The antibodies on the PROT20 column are specific for depletion of human plasma proteins. We would not recommend this product for other species. The PROTBA is a more economical possibility to try, even though that depletes only two proteins from serum.

  4. Are the Product PROT20, ProteoPrep Plasma Immunodepletion Kit, columns available as stand-alone products?

    The columns are not available separately from the kit. The only kit components available separately are CLS8160 and M0286. We offer a smaller scale kit, PROT20S, which has one column instead of 3.

  5. Is there a point in the protocol for Product PROT20, ProteoPrep Plasma Immunodepletion Kit, where I can stop in the middle?

    In general, it is best to complete the depletion procedure once it is started. However, the customer can, if necessary, stop the procedure after the primary depletion and store the depleted samples frozen. The customer can then elute the bound proteins from the resin later and reuse it for re-depletion of the sample.

  6. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  7. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  8. How do I find price and availability?

    There are several ways to find pricing and availability for our products. Once you log onto our website, you will find the price and availability displayed on the product detail page.

Candidate proteomic biomarker discovery from human plasma holds both incredible clinical potential as well as significant challenges. The dynamic range of proteins within plasma is known to exceed 10(10), and many potential biomarkers are likely present at lower protein abundances.
