Figure 2From: Novel protein extraction approach using micro-sized chamber for evaluation of proteins eluted from formalin-fixed paraffin-embedded tissue sections Illustration of the recovery process for antigen-retrieval buffer in the micro-sized chamber. The antigen-retrieval buffer was added to the micro-sized chamber adhered to the slide, and then sealed with a film cover. After HIAR, the antigen-retrieval buffer (supernatant) was recovered with a pipette.Back to article page
