H\u00e4ufig gestellte Fragen<\/h2>\n
\n

Was ist K\u00e4lberserum, und wie unterscheidet es sich von FKS und Neugeborenen-K\u00e4lberserum?<\/p>\n

K\u00e4lberserum (CS) wird von K\u00e4lbern im Alter von 14 Tagen bis 6 Monaten gewonnen \u2013 \u00e4lter als die F\u00f6ten f\u00fcr FKS und j\u00fcnger als ausgewachsene Rinder. Es enth\u00e4lt mehr Gesamtprotein und IgG als FKS und etwas weniger Wachstumsfaktoren, f\u00f6rdert das Wachstum der meisten etablierten immortalisierten Zelllinien aber gleichwertig oder nahezu gleichwertig. Neugeborenen-K\u00e4lberserum (NCS, \u226410 Tage) hat weniger IgG und etwas mehr Wachstumsfaktoren als CS; NCS ist vorzuziehen, wenn ein niedriger IgG-Hintergrund wichtig ist, CS ist die bessere Wahl, wenn maximale Kosteneffizienz im Vordergrund steht.<\/p>\n<\/div>\n

\n

Kann K\u00e4lberserum FKS in bestehenden Zellkulturprotokollen direkt ersetzen?<\/p>\n

F\u00fcr die meisten immortalisierten Standardzelllinien (CHO, HeLa, Vero, HEK293, BHK-21, MDCK, 3T3) l\u00e4sst sich CS in gleicher Konzentration (5\u201310 %) direkt statt FKS einsetzen. Eine kurze Adaptationsphase von 2\u20133 Passagen wird empfohlen, um Wachstumskinetik und Viabilit\u00e4t zu best\u00e4tigen. F\u00fcr Prim\u00e4rzellen, Stammzellen oder Anwendungen, die das spezifische Wachstumsfaktorprofil von FKS erfordern, wird CS nicht empfohlen.<\/p>\n<\/div>\n

\n

Wie ist der BSE\/TSE-Status von K\u00e4lberserum aus den USA?<\/p>\n

K\u00e4lberserum aus den USA wird in nach USDA 9CFR lizenzierten Einrichtungen gewonnen und mit einem 9CFR-Analysenzertifikat geliefert. Die USA haben den BSE-Risikostatus \u201ekontrolliert\u201c (OIE-Einstufung). Eine TSE\/BSE-Risikobewertung ist f\u00fcr Zulassungsunterlagen auf Anfrage erh\u00e4ltlich. F\u00fcr Anwendungen, die eine Dokumentation mit vernachl\u00e4ssigbarem BSE-Risiko erfordern, empfehlen wir unser K\u00e4lberserum Herkunft Australien.<\/p>\n<\/div>\n

\n

Gibt es K\u00e4lberserum aus den USA auch hitzeinaktiviert?<\/p>\n

Ja \u2013 eine Hitzeinaktivierung (56 \u00b0C, 30 min) ist auf Anfrage m\u00f6glich. Sie inaktiviert Komplementproteine und wird f\u00fcr komplementempfindliche Zellkulturanwendungen und immunologische Assays empfohlen. Sie ist im Chargen-CoA dokumentiert.<\/p>\n<\/div>\n

\n

Welche Dokumentation erhalte ich zu K\u00e4lberserum US-Herkunft?<\/p>\n

Jede Bestellung enth\u00e4lt ein Analysenzertifikat (CoA) und das USDA-9CFR-CoA. Weitere Dokumente \u2013 TSE\/BSE-Erkl\u00e4rung, Herkunftszertifikat (CoO), Sicherheitsdatenblatt (SDS), Pr\u00fcfprotokolle zu Sterilit\u00e4t und Mykoplasmen \u2013 auf Anfrage. Die Produkte werden in nach ISO 9001 und ISO 13485 zertifizierten Partnerwerken gehandhabt.<\/p>\n<\/div>\n
