Purity:

Greater than 85% as determined by SDS-PAGE.

Form:

Liquid or Lyophilized powder

Buffer:

If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.

Research Areas:

Microbiology

Function:

Involvement in disease:

Relevance:

A transpeptidase that forms peptide cross-links between adjacent glycan strands in cell wall peptidoglycan (PG). Part of the divisome machinery that synthesizes the septal cross wall. Beta-lactams inactivate the PBPs by acylating an essential serine residue in the active site of these proteins.

Reconstitution:

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.
