product information

Gene Transfer Agents (GTAs) are bacteriophage-like particles which function as a means to package and transfer genomic DNA between bacterial cells.GTA-mediated gene transfer might be an important phenomenon in natural microbial communities.


KLH-conjugated conserved peptide sequence found in the Gene Transfer Agent (GTA) major capsid protein (MCP) encoded in Bacteria within the Rhodobacterales order of the class alpha-Proteobacteria including Rhodobacter sphaeroidesQ3J3K4


Host Rabbit
Clonality Polyclonal
Purity Serum
Format Lyophilized
Quantity 200 ĩl
Reconstitution For reconstitution add 200 ĩl of sterile distilled water

store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

application example


Roseobacter capsulatus cells, pelleted by centrifugation and resuspended in an equial volume of TE buffer and supernatant sample* were separated on  10% SDS-PAGE and blotted 1h to nitrocellulose. The "+" indicated R. capsulatus SB1003 (GTA positive) and "-" indicated R. capsulatus A1 (GTA capsid protein negative). Blots were blocked in 5% skim milk in TBST followed by incubation with anti-GTA antibodies (AS08 365) at dilution 1: 1000 at 4°C over night. After washes blots were incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Santa Cruz Biotechnology, Santa Cruz, CA) and specific bands were detected with SuperSignal West Femto (Pierce Biotechnology).Exposure time was 30 seconds with CCD camera.

* - supernatant sample was obtained in a following way: cells were removed by two rounds of centrifugation at 17,000 g for 2 min. with sub-sample of the supernatant removed to a new tube. Two volumes of the cells or final culture supernatant were mixed with 1 volume of  3X SDS-PAGE sample buuffer (NEB).
