AVAILABLE TO ORDER
GRADE & PURITY Bioactive ? Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure. Recombinant ? Recombinant — produced via recombinant expression for defined sequence and consistency. Use for reproducible, animal-free proteins of known origin. ActiBioPure™ ? ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required. High Performance ? High-performance grade with optimized purity and performance characteristics. Use for sensitive analyses where ordinary grades fall short. EnzymoPure™ ? EnzymoPure™ — Aladdin's line of high-quality enzymatic solutions. Use when enzyme purity and defined activity drive assay or process performance. ≥85%(SDS-PAGE) ≥1 U/mg protein; Protein concentration: See COA; expressed in E.coli

Overview

β-1,3-Galactosyltransferase (CgtB), EC 2.4.1.62, is derived from Campylobacter jejuni. This enzyme transfers galactose (Gal) to N‑acetylgalactosamine (GalNAc) and oligosaccharides with GalNAc at the non‑reducing end via a β‑1,3‑glycosidic linkage. This product is recombinantly expressed in Escherichia coli with high enzymatic activity.

Recommended Reaction Equation

GalNAc + UDP‑Gal → Gal(β1‑3)GalNAc + UDP

Usage Instructions

  1. Add substrates to the reaction system together with 5 mM MgCl₂. Appropriate buffer salts such as Tris‑HCl may be supplemented to adjust the pH to 7.5, then add an appropriate amount of CgtB according to reaction requirements.

  2. After mixing, incubate the sample at 37 °C for 2–4 hours or overnight.

Note: For scaled‑up reactions, incubation time or enzyme dosage should be adjusted according to practical conditions; low‑speed shaking can be used for homogenization.

Precautions

For your safety and health, wear a lab coat and disposable gloves during operation. This product is for research use only.
