The CBS gene encodes cystathionine β-synthase (CBS), a core enzyme in methionine’s transsulfuration pathway. Common aliases include CBS enzyme or cystathionine synthase. It catalyzes serine and homocysteine condensation into cystathionine, a key step in homocysteine catabolism and cysteine biosynthesis, maintaining homocysteine homeostasis.
CBS dysfunction causes hyperhomocysteinemia, associated with cardiovascular diseases (atherosclerosis, stroke) and neurological disorders (Alzheimer’s, epilepsy). Vitamin B6 supplementation (CBS relies on pyridoxal phosphate, a B6 derivative) is a standard treatment. Recent research focuses on small-molecule activators to boost CBS activity for managing homocysteine-related pathologies.
Recombinant Human Cystathionine beta-synthase (CBS), partial (CSB-EP004589HU)
Validated Data
(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
Based on the SEQUEST from database of E.coli host and target protein, the LC-MS/MS Analysis result of CSB-EP004589HU could indicate that this peptide derived from E.coli-expressed Homo sapiens (Human) CBS.

IHC image of CSB-RA242578A0HU diluted at 1:100 and staining in paraffin-embedded human liver tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.05% DAB.

Overlay Peak curve showing SH-SY5Y cells stained with CSB-RA242578A0HU (red line) at 1:100. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100 for 10min. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1ug/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated goat anti-rabbit IgG (H+L) at 1/200 dilution for 35min at 4℃.Control antibody (green line) was Rabbit IgG (1ug/1*106cells) used under the same conditions. Acquisition of >10, 000 events was performed.
