Bovine Serum Albumin (BSA)
Bovine Serum Albumin (BSA) is a non-glycosylated protein of 66 kDa. Albumin is the main carrier for low molecular weight compounds such as fatty acids and hormones.
Roles:
Protein standard, stabilizer and blocking or buffering agent
Applications:
Blood grouping, cell culture or immunoassays (ELISA, RIA…)
Our method:
Heat Shock Method, the least denaturing method on the market, prevent the excessive use of organic solvents, 3 hours at 65°C
Source of our bovine plasma:
Collected from French healthy cattle declared free from BSE disease in its clinical forms
A complete line in both liquid (30% ready-to-use solution) or lyophilized forms, with different particularities.
Our expertise is at your service to develop a customized BSA.
Microbiological Ingredients
Bovine Fibrinogen & other RPF components
Especially developed for producing RPF supplement (Rabbit Plasma Fibrinogen) in addition to Baird Parker agar
SEQENS IVD also offers other RPF components separately such as Rabbit Plasma and Soybean Trypsin Inhibitor.
Roles:
Detection and enumeration of coagulase-positive staphylococci
Applications:
Food industry (ISO 6888-2) and in water testing controls (NF T90-412)
Our method:
Purification by Cohn fractionation
Source of our bovine plasma:
Collected from French healthy cattle declared free from BSE disease in its clinical forms
A complete line with a ready-to-use solution and a lyophilized powder, with different specifications.
The 5% frozen sterile solution enables to save time and cost of solubilization and filtration (0.2 µm).
Calibrators & Negative Controls Ingredients
Human Plasma and Serum
Roles:
Base matrix for calibrators, controls and standards
Applications:
Immunoassays (ELISA, Western blot …)
Source of Human Plasma and Serum:
Collected in EU licensed donation facilities, in accordance with ethical requirement of French Public Health.
Viral testing negative for:
Anti-HIV 1+2 & anti-HCV antibodies, HBs antigen, HIV 1 & HCV RNA, Syphilitic serology
A complete line available in units or pooled, with a possible selection on gender or blood group (AB male available).
Defibrinated Human Plasma
This product line is obtained from human plasma which was defibrinated. For improved stability and to facilitate filtration, we also offer a reference which was delipidated in addition.
SEQENS IVD offers physiologic and calibrated base matrices.
SEQENS IVD Defibrinated Plasma is a cost-effective substitute to off-the-clot serum.
Roles:
Negative controls
Applications:
Immunoassays (ELISA, Western blot …)
Source of Human Plasm:
Collected in EU licensed donation facilities, in accordance with ethical requirement of French Public Health.
Viral testing negative for:
Anti-HIV 1+2 & anti-HCV antibodies, HBs antigen, HIV 1 & HCV RNA, Syphilitic serology
A line with different particularities.
Human Processed Sera
Roles:
Calibrators
Applications:
Immunoassays in endocrinology and fertility testing (for example)
Our method:
Human plasma, successively defibrinated, dialysed, delipidated and then charcoal stripped to remove specific elements (vitamin D, steroids, hormones, T3/T4, TSH).
Source of Human Serum:
Collected in EU licensed donation facilities, in accordance with ethical requirement of French Public Health.
Viral testing negative for:
Anti-HIV 1+2 & anti-HCV antibodies, HBs antigen, HIV 1 & HCV RNA, Syphilitic serology
A line with different particularities
Cell Culture Ingredients
Human AB Male Serum
Immunoreactivity is minimised with AB blood group serum because this serum is free of antibodies to type A and B antigens.
Roles:
Growth supplement
Applications:
Mammalian cell culture and immunoassays
Our method:
The natural coagulation process of human blood, without anticoagulants only from male donors of blood group AB.
Source of Human Serum:
Collected in EU licensed donation facilities, in accordance with ethical requirement of French Public Health.
Viral testing negative for:
Anti-HIV 1+2 & anti-HCV antibodies, HBs antigen, HIV 1 & HCV RNA, Syphilitic serology
A line with different particularities.
Animal Sera
Roles:
Growth supplement (combination of proteins, amino acids and hormones)
Applications:
Cell culture, immunohistochemistry and immunofluorescence
A broad portfolio of animal sera in our brochure including bovine, rabbit, sheep, goat, horse, guinea pig, mouse, rat and chicken.
