[0044] 3. Preparation of anti-rhTNF-α monoclonal antibody

[0045] Select female Balb / c mice aged 8-10 weeks, and inject 0.5 ml of liquid paraffin into each intraperitoneal injection. One week later, 1×10 anti-rhTNF-α hybridoma cells were injected intraperitoneally. 6 After ascites was produced in the mouse peritoneal cavity (about 8-12 days), the ascites was taken from the mouse peritoneal cavity, and then centrifuged at 3000 rpm for 20 minutes to separate the ascites, and stored at -80°C for future use.

[0046] 4. Purification process of anti-human TNF-α monoclonal antibody

[0047] ①Principle

[0048] Q-SePharose Fast Flow is a strong anion exchange medium with the characteristics of fast flow rate and high capacity. The PI range of mouse IgG is pH 7.0-8.5, while the PI range of albumin and transferrin is pH 4.7-5.0, so Q-SePharose Fast Flow tends to bind non-targeted substances in ascites in a neutral pH environment. protein. When eluted with a salt solution gradient...

Abstract

The invention discloses an ointment based on an anti-TNF-alpha monoclonal antibody used for treating psoriasis, and the ointment comprises the following ingredients by weight: 0.33-0.5 part of anti-TNF-alpha monoclonal antibody, 1.5-2.5 parts of acryloyl dimethyl taurine ammonium / VP copolymer (AVC), 4-6 parts of polyethylene glycol4000, 4-6 parts of glycerol, 0.02-0.04 part of preservative and 85.127-89.98 parts of water. The ointment based on anti-TNF-alpha monoclonal antibody used for treating psoriasis enables the therapeutic effect without adverse reaction caused by using the anti-TNF-alpha antibody by whole body.

Description

technical field [0001] The invention relates to an ointment for treating psoriasis based on anti-TNF-α monoclonal antibody. Background technique [0002] Tumor necrosis factor (TNF-α) is a cytokine with complex biological activities, mainly produced by macrophages and T cells. In addition to killing tumor cells in vivo or in vitro, this substance also has multiple functions such as antiviral infection, activation of macrophages and polymorphonuclear granulocytes, promotion of expression of histocompatibility antigens, and regulation of the body's immune function. However, when TNF-α is overexpressed, it together with other inflammatory factors will produce various pathological damages, such as autoimmune diseases, infectious diseases, dyscrasias and so on. Therefore, neutralizing the excess TNF-α in the body can provide an effective way for the treatment of the above diseases. Current TNF-α antagonist drugs include Infliximab (Humiral), Etanercept (Enbel), Adalimumab (Remi...
