Application

Detects glycoproteins containing β(1→4)-N-acetyl-D-glucosamine when used with appropriate peroxidase substrate
General Western Blot Protocol:
  • Glycoprotein sample size: 500ng
  • Lectin Concentration: 0.1ug/ml

  1. Load samples at 500 ng of glycoprotein per lane
  2. Run 4-20% Bis-Tris SDS page gel
  3. Transfer gel to a PVDF membrane
  4. Block membrane for 1 hr at RT with RIPA buffer (R0278 Sigma)
  5. Incubate HRP lectin at 0.1ug/ml with RIPA buffer for 2 hours at RT
  6. Wash membrane 5 x 5 minutes with 25ml RIPA buffer
  7. Detect using chemiluminescent substrate (CPS1-120)

Biochem/physiol Actions

WGA is not blood group specific but has an affinity for N-acetyl-β-D-glucosaminyl residues and N-acetyl-β-D-glucosamine oligomers. WGA contains no protein-bound carbohydrate.

Packaging

Package size based on protein content.

Unit Definition

One unit will form 1.0 mg of purpurogallin from pyrogallol in 20 sec at pH 6.0 at 20 °C.

Physical form

Contains citrate buffer

Preparation Note

Conjugates are prepared from affinity purified lectin.
Prepared from peroxidase type VI (P8375) using a modification of the method of O′Sullivan, which favors low molecular weight conjugates. Repurified after conjugation by affinity chromatography.

Inhibition of encystment can be conceived as a potentially useful mechanism to block the transmission of Entamoeba histolytica under natural conditions. Unfortunately, amoeba encystment has not been achieved in vitro and drugs inhibiting the formation of cysts are not available.

The high antibiotic tolerance of Staphylococcus aureus biofilms is associated with challenges for treating periprosthetic joint infection. The toxin-antitoxin system, YefM-YoeB, is thought to be a regulator for antibiotic tolerance, but its physiological role is unknown. The objective of this

ATP-citrate lyase (ACLY), generating most of the nucleocytosolic acetyl coenzyme A (acetyl-CoA) for histone acetylation, links cell metabolism to epigenetic regulation. Recent investigations demonstrated that ACLY activated by metabolic reprogramming played an essential role in both M1 and M2 macrophage

Glycosylation defects are a hallmark of many nervous system diseases. However, the molecular and metabolic basis for this pathology is not fully understood. In this study, we found that N-linked protein glycosylation in the brain is metabolically channeled to glucosamine
