产品介绍

Alias	Alpaca IgG Native Protein, alpaca control antibody, alpaca isotype control
Catalog Number	TKPA101
Host	Alpaca
Size	1mg,5mg,10mg
Clonity	Polyclonal
Purity	>90%
Concentration	1mg/ml
Purification	IEX+Affinity purification
Formulation	150mM Nacl+0.1M Gly, pH7.0
Background	Three subclasses of IgG can be isolated from the serum of camelids. Conventional IgG1 contains molecules of ~170KD, which upon reduction yield 50KD heavy chains and large 30KD light chains. IgG2 and IgG3 are distinct in that they do not incorporate light chains. The IgG2 contain molecules of ~100KD, which upon reduction yield only heavy chains of ~49KD. The IgG3 contain molecules of ~90KD, which upon reduction yield only heavy chains of ~46KD. Alpaca Total IgG (TKPA101) is an isotype control antibody, which can be used as negative controls to help differentiate non-specific background signal from specific antibody signal.
Tag	Unconjugated

FAQ

Q1- 该产品的主要用途是什么？

①纳米抗体（VHH）开发：作为总IgG来源构建噬菌体展示文库，筛选单域抗体。②免疫检测：作为二抗（如HRP标记）检测羊驼来源的一抗，适用于ELISA、Western blot等实验。
Q2- 是否包含所有IgG亚型？

是，包含IgG1、IgG2和IgG3三种亚型，覆盖羊驼IgG的完整群体。
Q3- 如何保存？

①液体形式：4℃保存6个月（含0.05% NaN₃），长期保存需分装-20℃（含50%甘油）。②冻干粉：-80℃保存5年，复溶后4℃保存1周。
Q4- 是否与其他物种IgG交叉反应？

仅特异性结合羊驼IgG，与人、小鼠、大鼠IgG无交叉反应（经ELISA验证）。
Q5- 是否适配噬菌体展示文库构建？

是，适用于免疫后外周血单核细胞（PBMC）的mRNA提取及VHH文库构建。
