(Adds comments, background)

FRANKFURT, Aug 11 (Reuters) - Stricken German private bank Sal. Oppenheim has raised its equity capital by 300 million euros ($425 million) to around 2.1 billion euros, it said on Tuesday.

"The injection was made by shareholders and financed by Deutsche Bank," it said on its website.

Sources familiar with the situation had told Reuters on Monday that Deutsche Bank (DBKGn.DE) would support the capital increase.

In addition, Deutsche Bank could buy shares from some of Sal. Oppenheim's current owners, they said.

"Overall, Deutsche Bank is aiming for a stake in Sal. Oppenheim of between 30 percent and slightly less than 50 percent at first," one of the sources had said.

Sal. Oppenheim confirmed last week it was in talks for a "strategic partnership" with Deutsche Bank and that Germany's flagship lender will be allowed to conduct due diligence, but declined to give details on the proposed transaction.

It said on Tuesday that the capital increase was the first step in that process.
