赛默飞明矾佐剂(铝佐剂)停产后,还有哪些品牌的明矾佐剂值得购买?

赛默飞公司的名字,在生物行业里面,可以媲美中国的华为,小米等品牌知名度。基本上国内大部分的生物公司,医药公司,或者是科研单位等,对赛默飞这个品牌,都是耳熟目染的。那么近期有科研的老师在查找赛默飞明矾佐剂时,发现赛默飞已经停止了该产品的销售,想问下我们上海金畔生物公司,在代理的品牌中,有没有合适的明矾佐剂值得推荐或者是购买的?

(赛默飞官网显示明矾佐剂停产通知)

上海金畔生物成立于2007年,在生物行业已经有16年的历史了,可谓也是跟上了国内生物行业兴起的潮流,在生物行业有自己的一席之地。那么该老师也是出于对金畔品牌的信任,才会前来咨询。

其实我们金畔一直有售卖Invivogen品牌的明矾佐剂,InvivoGen公司的佐剂,有得到德国联邦机构评估,并且该明矾佐剂,有被文献引用,具体详情大家可以前往查看《德国联邦机构评估InvivoGen佐剂》这篇文章, 网址http://www.jinpanbio.com/xwzx_1723.html,里面介绍的比较详细。下面给大家详细介绍一下Invivogen品牌的明矾佐剂:

Alhydrogel® adjuvant 2%产品介绍:

该佐剂是一种氢氧化铝凝胶悬浮液,也被称为明矾,主要通过在注射部位形成储库来发挥作用,即将抗原固定在注射部位,让其缓慢释放从而达到持续刺激免疫系统的作用,从而增强抗原的可用性。

明矾通过增强抗原递呈细胞(APCs)对抗原的募集和活化来诱导Th2免疫反应,还可以激活由模式识别受体(PRRs)触发的先天免疫途径。

与磷酸铝凝胶不同的是,氢氧化铝凝胶颗粒在pH5-7时具有净正电荷,因此非常适合吸附带负电荷的抗原(例如:等电点低于制剂pH的抗原)。

Storage: Upon receipt store at room temperature. Product shipped at ambient temperature.
Note: This product is supplied for research or manufacturing applications only and is not intended for clinical use.
Introduction:
Generating a strong immune response with immunogens can be a slow and inefficient process. Adding an adjuvant, such as Thermo Scientific Imject Alum, to the antigen stimulates an improved immune response compared to the antigen alone. Adjuvants increase the immune response by localizing antigen for an extended time and attracting the appropriate cells (T cells, B cells and APC) to interact with the immunogen and each other. Adjuvants are mixed and injected along with antigen to prevent catabolism.
Alum is frequently used as an alternative to Freund’s adjuvants because alum is less hazardous. Although Freund’s complete and incomplete adjuvants produce a stronger, longer lasting immunogenic response compared to other adjuvants, they are hazardous to the researcher and can produce lesions at the injection site.
A traditional drawback when using alum is the reagent preparation time; however, Imject Alum is preformulated and simply requires mixing with the antigen and then injection into the animal. Imject Alum provides an effective and convenient alternative to the more hazardous Freund’s reagents. This product can be used with any immunogen kit for preparing hapten-carrier conjugates.
Protocol for Mixing Immunogen with the Imject Alum
Note: To avoid anaphylaxis, do not use adjuvants for intravenous injection.
1.Shake the capped bottle of Imject Alum well before use.
2.Add Imject Alum dropwise with constant mixing to the immunogen solution so the final volume ratio of Imject Alum to immunogen is 1:1 (e.g., add 100μL of Imject Alum to 100μL of immunogen) to 1:3 (e.g., add 100μL of Imject Alum to 300μL of immunogen solution).
3.Continue mixing for 30 minutes after adding the Imject Alum. Mixing allows the Imject Alum to effectively adsorb antigen.
4.Immunize animal according to standard protocol (see Harlow and Lane, 1988, for more information). The immunogen concentration before mixing with alum and the species being tested will determine injection amount. Generally, 50-100μg of immunogen is used per mouse per immunization. Rabbits require 100μg of immunogen per injection at each subcutaneous site. For rabbit or mouse, a typical concentration of immunogen (before mixing with Imject Alum) is 100μg per 100μL.
