产品描述 概述Viral MIP-2 is one of the three chemokine-like proteins expressed by the human herpesvirus 8 (Kaposis sarcoma-associated herpesvirus, KSHV) and the other is ViMIP-1 and ViMIP-3. It shares 41 % and 48 % with human MIP-1α and ViMIP-1, respectively. ViMIP-2 has been shown to have antagonist activity towards a wide range of chemokine receptors and has functions of blocking infection by several different human immunodeficiency virus type 1 (HIV-1) strains. It may form part of the response to host defenses contributing to virus-induced neoplasia and may have relevance to KSHV and HIV-I interactions. Additionally, ViMIP-2 has been shown to activate and chemoattract human eosinphils. 使用说明This material is offered by Novin Biotech for research, laboratory or further evaluation purposes. NOT FOR HUMAN USE. 技术规格| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. | | Purity | > 97 % by SDS-PAGE and HPLC analyses. | | Source | Escherichia coli. | | Biological Activity | Fully biologically active when compared to standard. The specific activity is determined by the inhibitory effect on monocyte migration response to human MIP-1 alpha using a concentration range of 1.0μg-10.0μg/ml of viral MIP-2 will inhibit 25ng/ml of human MIP-1 alpha. | | Formulation | Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 150mM NaCl. | | Endotoxin | Less than 1 EU/μg of rViMIP-2 as determined by LAL method. | | Reconstitution | We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 C. Further dilutions should be made in appropriate buffered solutions. | | AA Sequence | LGASWHRPDK CCLGYQKRPL PQVLLSSWYP TSQLCSKPGV IFLTKRGRQV CADKSKDWVK KLMQQLPVTA |
