Why do different bottles of human serum sometimes look different from one another?
Gemini Bio-Products goes to great lengths to ensure that our human sera are the most consistent products commercially available. Although our human serum is manufactured using raw material from congruous donor pools and according to time-tested protocols, it is possible to perceive differences in the physical appearance of this product from lot-to-lot. This phenomenon can be largely attributed to variation in diet amongst human beings (particularly with respect to dietary fats). Another source for slight differences comes from non-uniform storage conditions and/or handling variations in the laboratory setting. Due to the special sensitivity of this product (as compared to other sera), it is critical that human serum be cared for as recommended by the manufacturer.
