Hi Miss/sir, I got a chemical named as HMGB1 peptide(ab18650) from abcam. There seems to be a doubt in its storage buffer marked in red as follows? What is the unit of 20 HEPES? Storage buffer Preservative: None Constituents: 0.001% Tween 20, HEPES, 2mM EDTA, 150mM Sodium chloride Thanks. Best regards.

Thank you for contacting us. The storage buffer for ab18650 is as follow: 30mM Hepes 150mM NaCl 2mM EDTA 0.001% Tween 20 pH 6.75 Therefore the Hepes concentration is 30mM and "Tween 20" is a detergent with a concentration of 0.001%. I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
