Recombinant Human B7‑1/CD80 Fc Chimera (Catalog&amp;nbsp;# 140-B1) co-stimulates IL‑2 secretion in the Jurkat human acute T cell leukemia cell line in the presence of PHA in a dose-dependent manner (orange line), as measured by the Human IL‑2 Quantikine ELISA Kit (Catalog&amp;nbsp;# D2050). IL‑2 secretion elicited by Recombinant Human B7‑1/CD80 Fc Chimera (1&amp;nbsp;µg/mL) and PHA (10&amp;nbsp;µg/mL) is neutralized (green line) by increasing concentrations of Mouse&amp;nbsp;Anti-Human B7‑1/CD80 Monoclonal Antibody (Catalog&amp;nbsp;# MAB140).

Novus, like many others companies such as Abcam, Covance, Proteintech Group, EnCor Biotechnology and Millipore Corporation, arose to answer a call for research grade antibodies for the scientific market.Founded by Karen Padgett in 1996, Novus Biologicals has sought to partner with leading scientific researchers and third-party providers to develop an extensive range of more than 180,000 products.[2] The main products are antibodies, proteins, peptides, RNAi, cell lysates, isotype controls, slides, and kits. Padgett is company president and CEO, and has been active both in the academic and local Colorado communities. In 2008, Novus became a limited liability company when Mainsail Partners invested in the company.[4] Novus Biologicals has reported double digit revenue growth every year since its inception, has been selected six years in a row to the Inc. (magazine) 5000 fastest-growing private companies in America,[5] and was on the 2009 list of Colorado Companies to Watch.[6]In 2014 major antibody and reagent supplier Bio-Techne, acquired Novus Biologicals for $60 million.[7] The acquisition was meant to provide scientists and doctors a broader selection of products in one location. 产品列表： Novus-Biologicals SP4385P MC1 Receptor Antibody 0.05mg Novus-Biologicals PA184X Defensin beta 3 Protein 0.02mg Novus-Biologicals NSB998 PKA 2 beta [phospho Ser114] Antibody 0.1ml Novus-Biologicals NSB992 cAMP Protein Kinase Catalytic subunit beta [phospho Ser338] Antibody 0.05ml Novus-Biologicals NSB988 cAMP Protein Kinase Catalytic subunit alpha [phospho Thr197] Antibody 0.1ml Novus-Biologicals NSB979 PKC theta [phospho Ser695] Antibody 0.1ml Novus-Biologicals NSB978 PKC eta [phospho Ser674] Antibody 0.1ml Novus-Biologicals NSB977 PKC epsilon [phospho Ser729] Antibody 0.1ml Novus-Biologicals NSB976 PKC delta [phospho Ser664] Antibody 0.1ml Novus-Biologicals NSB975 PKC gamma [phospho Thr674] Antibody 0.1ml Novus-Biologicals NSB970 PKC theta [phospho Ser676] Antibody 0.1ml Novus-Biologicals NSB969 PKC eta [phospho Thr655] Antibody 0.1ml Novus-Biologicals NSB968 PKC iota [phospho Thr555/Thr563] Antibody 0.1ml Novus-Biologicals NSB966 PKC delta [phospho Ser645] Antibody 0.1ml Novus-Biologicals NSB965 PKC gamma [phospho Thr655] Antibody 0.1ml Novus-Biologicals NSB964 PKC beta [phospho Thr641] Antibody 0.1ml Novus-Biologicals NSB963 PKC beta [phospho Thr642] Antibody 0.1ml Novus-Biologicals NSB962 PKC alpha [phospho Thr638] Antibody 0.1ml Novus-Biologicals NSB961 PKC mu [phospho Ser738/Ser742] Antibody 0.1ml Novus-Biologicals NSB960 PKC theta [phospho Thr538] Antibody 0.1ml Novus-Biologicals NSB956 PKC gamma [phospho Thr514] Antibody 0.1ml Novus-Biologicals NSB955 PKC beta [phospho Thr500] Antibody 0.1ml Novus-Biologicals NSB948 GATA4 [phospho Ser105] Antibody 0.1ml Novus-Biologicals NSB944 NFAT1 [phospho Ser54] Antibody 0.1ml Novus-Biologicals NSB942 PAK1/2/3 [phospho Thr423] Antibody 0.1ml Novus-Biologicals NSB940 PAK1/2/3 [phospho Ser141] Antibody 0.1ml Novus-Biologicals NSB928 RSK1 [phospho Ser380] Antibody 0.1ml Novus-Biologicals NSB926 RSK1 [phospho Ser363] Antibody 0.1ml Novus-Biologicals NSB924 RSK1 [phospho Ser221] Antibody 0.1ml Novus-Biologicals NSB923 RPS6 [phospho Ser244/Ser247] Antibody 0.1ml Novus-Biologicals NSB922 RPS6 [phospho Ser235/Ser236] Antibody 0.1ml Novus-Biologicals NSB921 RPS6 [phospho Ser236] Antibody 0.1ml Novus-Biologicals NSB918 S6K [phospho Thr229] Antibody 0.1ml Novus-Biologicals NSB912 Src [phospho Tyr522] Antibody 0.1ml Novus-Biologicals NSB910 Hck [phospho Tyr207/Ser211] Antibody 0.1ml Novus-Biologicals NSB909 DAB1 [phospho Ser491] Antibody 0.1ml Novus-Biologicals NSB908 DAB1 [phospho Tyr220] Antibody 0.1ml Novus-Biologicals NSB906 DAB1 [phospho Tyr198] Antibody 0.1ml Novus-Biologicals NSB896 Met (c-Met) [phospho Tyr1365] Antibody 0.1ml Novus-Biologicals NSB892 Met (c-Met) [phospho Tyr1349] Antibody 0.1ml
