HSA Cell Culture Grade Lyophilized Recombinant Albumin Powder

CAS Number: 70024-90-7 | Brand: Anrate | Catalog No.: ART103S

Product Introduction

Anrate cell culture grade recombinant human albumin (rHSA) is a high-performance cell culture medium supplement engineered specifically for serum-free and chemically defined culture systems. Expressed in Pichia pastoris via recombinant DNA technology and purified through multi-step chromatography, this lyophilized powder delivers a consistent, animal-origin-free alternative to plasma-derived HSA and bovine serum albumin (BSA).

With precisely controlled quality specifications and low endotoxin levels, it supports robust cell growth, maintains cell viability and morphological uniformity, and minimizes experimental variation caused by batch-to-batch differences in serum-derived products. It is widely adopted in academic research, cell therapy development and biopharmaceutical production workflows.

Key Benefits for Cell Culture

Optimized for Serum-Free Systems

Formulated to support adhesion, proliferation and expansion of mammalian cells. Serves as a core nutrient carrier and osmotic stabilizer in chemically defined media, enabling reliable serum-free culture without performance compromise.

100% Animal-Origin-Free Process

Entire manufacturing chain uses no animal-derived raw materials. Eliminates risks of blood-borne pathogens, mycoplasma and xenogeneic protein interference, simplifying regulatory documentation for cell therapy and biologic development projects.

Ultra-Low Impurity Profile

≥99% purity verified by SDS-PAGE and HPLC, with endotoxin ≤0.5 EU/mg and minimal host cell residual. The clean formulation reduces cytotoxic interference and background noise in downstream assays.

Superior Batch-to-Batch Consistency

Industrial-scale fermentation and standardized purification ensure highly consistent product quality across production lots. This eliminates experimental variability caused by serum albumin batch differences and improves data reproducibility.

Easy-Use Lyophilized Format

Porous lyophilized cake dissolves rapidly at room temperature into a clear, particle-free solution. Ready for direct addition to culture media, suitable for both bench-scale research and large-volume bioproduction preparation.

Product Specifications

Application Areas

Serum-Free Cell Culture Media

Core additive for chemically defined and xeno-free media formulations, supporting routine culture of CHO, HEK293, VERO and other production cell lines.

Stem Cell & Immune Cell Research

Suitable for expansion of mesenchymal stem cells (MSCs), T cells, NK cells and iPSCs, helping maintain cell phenotype and differentiation potential during long-term culture.

Cell Cryopreservation Formulations

Key protective component in serum-free freezing media, reducing ice crystal damage and improving post-thaw cell recovery rate and viability.

Biologic R&D Excipient

Used as a stabilizer and protectant in protein reagent, antibody and vaccine formulation development, preventing protein aggregation and denaturation during storage.

In Vitro Diagnostic Assays

Blocking reagent and protein stabilizer for ELISA, lateral flow assays and Western blotting, reducing non-specific binding and improving assay precision.

Protein Storage & Handling

Protects recombinant proteins, enzymes and antibodies from surface adsorption and degradation during dilution, storage and transportation.
