Protein State


HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.This product is manufactured by and sold under license from OriGene Technologies and its use is limited solely for research purposes.

FAQs for COMP/Thrombospondin-5 Lysate (NBP2-09056). (Showing 1 - 1 of 1 FAQ).

  1. I have synovial fluid sample and I want to work on Western bloting can you support me,how can I prepare this sample for WB technique for assay comp(cartilage oligomatrix protein )?
    • We currently sell four antibodies to cartilage oligomeric matrix protein (COMP), all of which are validated for Western blotting. Although we have generated Western blot data using samples from human, bovine and rabbit cartilage, we do not have any testing data derived from synovial fluid samples. You may however find the following publication useful, in which the authors sampled synovial fluid from patients with rheumatoid arthritis and prepared this fluid for Western blot detection of the proteins SP-A and SP-D: PMC 2080374
