It is essentially free of HbA0. The purity is validated by HPLC, and reported concentration is determined by Drabkin’s assay.\u003c\/div\u003e\n\u003cdiv class=\"ewa-rteLine\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ewa-rteLine\"\u003eStorage \u0026amp; Handling: The material is supplied in liquid form in dilute potassium cyanide-phosphate buffer. The concentration varies with manufacturing lot, but the protein may be used directly by dilution in buffer in most experimental methods. It is shipped frozen at -20 C. Short term storage should be at 4 C. Long term storage should be -60 C. Repeated cycles of freezing and thawing should be avoided.\u003c\/div\u003e\n\u003cdiv class=\"ewa-rteLine\"\u003e\u003c\/div\u003e\n\u003cem\u003e\u003c\/em\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cem\u003eNot for use in the body.\u003c\/em\u003e \u003c\/div\u003e","brand":"Ethos Biosciences","offers":[{"title":"Default Title","offer_id":52440609489178,"sku":"HBA2","price":539.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1002\/7558\/5306\/files\/wp-image-11624404353124-scaled_71a28c1e-fd4a-4fdf-b90d-5858db58cd5e.jpg?v=1784918144","url":"https:\/\/shop.ethosbiosciences.com\/products\/human-hemoglobin-a1a-a1b-mixture-1-0-mg","provider":"Ethos Biosciences","version":"1.0","type":"link"}
