Protein Information
Accession Number:
- Q53707
Antibody Specifications
Applications:
ELISA (recommended work dilution= 1:40,000 (detects ? 25 µg/ml)) , Western Blotting (recommended work dilution= 1:1,000), (see image) Western blot analysis of 100 ng rPBP2a using purified rabbit anti-PBP2a primary antibody (1:1,000 µg/ml), Then the blot was incubated with anti-rabbit HRP-conjugated IgG (1:10,000).
Conjugation/Tag:
Biotin
Host Species:
Rabbit
Preparation:
The immunogen was a synthetic peptide (PBP2a: aa 475~498: NH2-CGSKKFEKGMKKLGVGEDIPSDYPF). This antibody was produced from a rabbit immunized with this peptide conjugated with KLH. The IgG fraction was purified from rabbit serum by Protein G affinity chromatography.
Reconstitution:
A separate vial of dilution buffer is provided for reconstitution. The antibody is supplied lyophilized, originally containing PBS, without preservative stabilizers (e.g. sodium azide). The final amount is indicated on the shipping vial.
Clonality:
Polyclonal
Isotype:
IgG
Description
Methicillin-resistant Staphylococcus aureus (MRSA) is a major pathogen responsible for serious hospital infections worldwide. These bacteria are resistant to all beta-lactam antibiotics due to the production of an additional penicillin binding protein, the PBP2a (about 75 kDa) encoded by the mecA gene, which shows low affinity for this class of antibiotics. According to the resistant and sensitive ability of the bacteria to antibiotics, two main groups are classified, MRSA and MSSA (Methicillinsensitive Staphylococcus aureus).
Storage / Stability
The antibody is stable for at least 1 year from the date of receipt when stored at -20°C to -70°C. Reconstituted antibody can also be aliquotted and stored at 4°C for 1 month or at -20°C to -70°C in a manual defrost freezer for many months without detectable loss activity. Please avoid freeze-thaw cycles.
Specificity
This antibody was selected for its ability to specifically detect PBP2a from MRSA. The antibody has ability to distinguish both MRSA and MSSA in tested assays; in Western Blot analysis, this antibody did not produce a band for any bacterial cell lysates from MSSA. This antibody showed no cross-reactivity with other tested bacterial proteins.
