Description

Methicillin-resistant Staphylococcus aureus, abbreviated MRSA, is one of a number of greatly feared strains of S. aureus which have become resistant to most B lactam antibiotics. Resistance is conferred by the mecA gene, which codes for an altered penicillin-binding protein (PBP2a or PBP2') that has a lower affinity for binding B lactams (penicillins,cephalosporins, and carbapenems). This allows for resistance to all B lactam antibiotics, and obviates their clinical use during MRSA infections.

This aptamer was selected by scientists at Base Pair Biotechnologies using proprietary methods and Recombinant Staphylococcus aureus PBP2a, [Ray Biotech Cat # 230-00051] as a target and 1X PBS, pH 7.4, 0.01% BSA, 0.002% Tween20.  Let us know if you have any questions about its development or potential uses.

Target:   PBP-2a, Penicillin-binding-protein 2a from Staphylococcus aureus

Target Species:   bacterial

Target Type:   protein

Affinity Constant (Kd):   23.5 nM

Aptamer information Kd 23.5 nM

Notes

Antibody Equivalent Units (AEU). There is a  large molecular weight difference in antibodies (typically 150,000 Da) and Base Pair’s aptamers (~14,000 Da). We provide our aptamers in terms of moles, where the aptamer moles in 1  AEU is equal to antibody moles in the typical 100 microgram shipment from a leading antibody vendor. Therefore our standard 2.5 AEU (25ug) or 5 AEU (50ug) delivery is 2.5 and 5 times the equivalent moles of a standard antibody delivery of 100 microgram respectively.
