I'm from Mexico and I would like some recommendations on brands of ELISA kits that measure cytokine/chemokine in plasma. As my question states, I am particularly interested in SDF-1/CXCL12 but I would appreciate feedback of your experience with ELISA kits of Latin American circulating brands even if for other proteins (reliability, cost/benefit, precoated vs DIY kits, etc.).

Thank you in advance
