描述

GALNTL1 protein plays a pivotal role in O-linked oligosaccharide biosynthesis by catalyzing the crucial initial step—the transfer of an N-acetyl-D-galactosamine residue to a serine or threonine residue on the protein receptor. This enzymatic activity is fundamental for the glycosylation processes that modulate the structure and function of various proteins, impacting diverse cellular functions. GALNTL1 Protein, Human (HEK293, His) is the recombinant human-derived GALNTL1 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of GALNTL1 Protein, Human (HEK293, His) is 532 a.a., with molecular weight of 62-65 kDa.

研究背景

GALNTL1 是 GALNT(N-乙酰半乳糖胺基转移酶)家族的成员,是一种在 O-连接寡糖生物合成起始中发挥关键作用的酶。具体来说,GALNTL1 催化 N-乙酰基-D-半乳糖胺 (GalNAc) 残基转移到蛋白质受体上的丝氨酸或苏氨酸残基。这个过程代表了蛋白质糖基化的第一步,其中将糖部分添加到特定的氨基酸残基上有助于细胞糖蛋白的多样性和复杂性。GALNTL1 的活性对于通过 O-连接糖基化修饰蛋白质至关重要,从而影响各种细胞过程和功能。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
