背景
Galectin-1 (Gal-1, GAL1), is a member of the galectins, a family of animal lectins ranging from Caenorhabditis elegans to humans, which is defined by their affinity for beta-galactosides and by significant sequence similarity in the carbohydrate-binding site. It is a homodimer with a subunit molecular mass of 14.5 kDa, which contains six cysteine residues per subunit. The cysteine residues should be in a free state in order to maintain a molecular structure that is capable of showing lectin activity. This endogenous lectin widely expressed at sites of inflammation and tumour growth, has been postulated as an attractive immunosuppressive agent to restore immune cell tolerance and homeostasis in autoimmune and inflammatory settings. On the other hand, galectin-1 contributes to different steps of tumour progression including cell adhesion, migration and tumour-immune escape, suggesting that blockade of galectin-1 might result in therapeutic benefits in cancer. Several potential glycoprotein ligands for galectin-1 have been identified, including lysosome-associated membrane glycoproteins and fibronectin, laminin, as well as T-cell glycoproteins CD43 and CD45. Evidence points to Gal-1 and its ligands as one of the master regulators of such immune responses as T-cell homeostasis and survival, T-cell immune disorders, inflammation and allergies as well as host-pathogen interactions.

Q1:重组蛋白有活性吗?可以做活性检测吗?

活性说明的见说明书bio-activity部分;如果说明书显示没有生物活性或则显示生物活性检测中,则说明这个蛋白没有生物活性数据,需要客户自己检测。

Q2:蛋白的运输条件是什么?

我们的蛋白有液体和冻干粉2种形式,一般来说冻干粉可以用冰袋、蓝冰、干冰运输;液体可以用蓝冰或干冰运输。

Q3:蛋白Buffer里是否含有denaturants(变性剂)?

我们在售重组蛋白一般不含变性剂,具体见说明书的formulation信息。常见变性剂有:尿素和盐酸胍。

Q4:蛋白是通过什么方式纯化的?

一般通过纯化标签进行亲和纯化,常规有镍柱/His Tag、protein AG/Fc tag、标签抗体凝胶等。

Q5:蛋白发货形式可以是冻干粉吗?可以发液体吗?

默认按照说明书标注的形式发货;如果有特殊需求,需要根据蛋白情况确定。原则上,冻干粉蛋白可以发液体形式,液体蛋白不能发冻干粉形式。

Q6:无标签蛋白纯化方式?

蛋白的纯化方式一般通过标签进行亲和纯化,无标签的蛋白是在纯化后进行了标签切除。

Q7:蛋白可以用于细胞培养/注射小鼠吗?

内毒素含量小于0.1 ng/μg (1 EU/μg)的蛋白都可以用于细胞培养/注射小鼠。
